Determine If Values In A Field Are Alpha Or Numeric
Feb 28, 2008
HI,
Thanks in advance for taking your time to read this post.
I am trying to write a SQL query using MS SQL 2005 that will read the value of a field and tell if it is alpha or numeric. I have tried the following but it does not work:
select field1 from table1 where left(field1,2)='[0-9]'
select field1 from table1 where isnumber(left(field1,2) tried with a =1 at the end and without and =1 at the end
the goal is to read through a field and format it so if a field looks like this 12xxx111xx I can change it to look like 12-xxx-111-xx.
Hi, I have a little bit of a problem I cannot seem to figure it out. Is it possible to write a Select statement that contains a WHERE column_name > desired_numeric_value The tricky part it that the column is of CHAR type and can contain numeric grades ranging from 0-100 or the letter I for Incomplete. My SQL was working perfect when this column contained only numbers as soon as a record with I was added I get the following error: Character to numeric conversion error This report will be used to find students who have failing grades. Thanks for any help!
hi , can anyone tell me if there exists a function in SQL Server that help me determine if a variable is ALL Alphanumeric data or not by returning a 0 or 1 when condition fails or succeeds . thank you
In SQL I need to be able to take a varchar parameter @Area and convert it to a float.
The input values for @Area I can't control. They can range from 6300 to 6,300 SqFt to 1.2 Acres .
So to convert this value to a float I basically look through the string and remove everything that isn't a number or a period. Then I would convert this value to square feet based on how large the number is.
select @k = patindex('%[^0-9. ]%', @Temp) while @k> 0 begin select @Temp = replace(@Temp, substring(@Temp, @k, 1), '') select @k= patindex('%[^0-9. ]%', @Temp) end
If @Temp = '' BEGIN SET @Temp = '0' END
SELECT @SqFt = Convert(Float, @Temp)
--Distinguish if it was acres or square feet If (@SqFt > 750.00) BEGIN SET @SqFt = @SqFt END ELSE BEGIN SET @SqFt = (@SqFt * Convert(Float,43560) ) END
SELECT @SqFt
This works great except for one situation, If @Area is something like 6,300 Sq.Ft. . When I run it through the part that removes all non-numeric items and periods, I end up with 6300 .. . So to get around this I want to find the first letter in the string and then remove everything after it. Then take the result and run it through part that removes everything but the numbers and period.
However I can't find away to get the index of the alpha-numeric character and remove everything after it.
We have a table with an indesx that is varchar(7). It contains up to 5 numbers and 2 characters to denote batches. IE. 100a 105zz 1c 2 10001w
In an Access gui I need to be able to sort this field numericaly so each number shows up in its correct position. IE. 1c 2 100a 105zz 10001w
In order to accomplish this, I created a seperate field on the table named Num as varchar(5). I would like to create a trigger that updates this field any time a new batch number is entered. This way I can have my queries order by Num when returning the recordsets to the GUI.
Below is the code that I thought would work, but it is giving me an error near the keyword BEGIN after the IF(ISNUMERIC) statement. I can't seem to find an error with this code, but I thought maybe a thousand fresh sets of eyes could. Any help would be greatly appreciated. Also if you know of a better way to accomplish this task, please feel free to post here.
TIA,
Aaron
CREATE TRIGGER [InsertNum] ON [dbo].[IP_Batch_Table_Temp] FOR INSERT, UPDATE AS
DECLARE @Num varchar(7) DECLARE @Num1 CHAR(7) DECLARE @x INT
SET @Num = (SELECT IP_Batch_Number FROM inserted) SET @x = 1 WHILE (@x < len(@Num)) BEGIN IF (ISNUMERIC( SUBSTRING(@Num, @x, 1) ) ) BEGIN SET @Num1 = @Num1 + SUBSTRING(@Num, @x, 1) END SET @x = @x + 1 END UPDATE IP_BATCH_TABLE_TEMP SET NUMBER = ltrim(rtrim(@Num1)) WHERE IP_BATCH_NUMBER = @Num
If I create an index on a field in SQL Server, what will be the most efficient (fastest) field type to index a field? (This field will be a "Pointer" to a child table that will contain a list of codes, and their description.) Would a Numeric field be quicker than a VarChar field? VarChar would make it easier for a Human to decipher the raw records. (For example, if I used a numeric the code would be 42 or 47, while the VarChar could be 'savings' or 'checking'.) Basically I will have the following "Master" table: FieldType --------- IDInt NameVarChar StatusInt -or- VarChar Customer_TypeInt -or- VarChar If Customer_Type is a code that can be looked up in another table, and I index that field, would I want the "Code" to be an Int or VarChar? SQL: Select * From Master Where Customer_Type = <42> or <'savings'> My Where clause would depend on the field type. Thank you, Bryan
I have a field defined as varchar(8) but this field should not contain any letters, needs to be only numbers. How can I validate the data if it contains only numbers? Any ideas?
I am putting a SELECT statement together where I need to evaluate a results field, to determine how the color indicator will show on a SSRS report. I am running into a problem when I try to filter out any non-numeric values from a varchar field, using a nested CASE statement.
For example, this results field may contain values of '<1', '>=1', '1', '100', '500', '5000', etc. For one type of test, I need a value of 500 or less to be shown as a green indicator in a report, and any value over that would be flagged as a red. Another test might only allow a value of 10 or less before being flagged with a red.
This is why I setup a CASE statement for an IndicatorValue that will pass over to the report to determine the indicator color. Using CASE statements for this is easier to work with, and less taxing on the report server, if done in SQL Server instead of nested SSRS expressions, especially since a variety of tests have different result values that would be flagged as green or red.
I have a separate nested CASE statement that will handle any of the values that contain ">" or "<", so I am using the following to filter those out, and then convert it to an int value, to determine what the indicator value should be. Here is the line of the script that is erring out"
case when (RESULT not like '%<%') or (RESULT not like '%>%') then CASE WHEN (CONVERT(int, RESULT) between 0 and 500) THEN '2' ELSE '0'
The message I am getting is: Conversion failed when converting the varchar value '<1' to data type int.
I thought a "not like" statement would not include those values for converting to an int, but that does not seem to be working correctly. I did also try moving the not to show as "not RESULT like", and that did not change the message.
How I can filter out non-numeric values before converting the rest of the varchar field (RESULT) to int, so that it is only converting actual numbers?
Karikalan writes "We need alpha numeric auto increment code in sql server 2000. (for eg.: ico1001, ico1002, ico1003,......) Can any one send the code in MS sql server 2000? plz .................. bcoz i am beginner in sqlserver 2000"
I need to strip out all alpha chars and spaces in a given field and return only the numbers.
I've tried =CInt(Fields!Info.Value) and get an unexplained error. If the data was formatted consitantly I could simply do a RTrim or Right, but the number strings are not the same, some have spaces as in phone numbers (1 800 555 1212) or don't have a leading 1. Most instances are correct for my purpose (8005551212).
Any help would be appreciated.
UPDATE: Using the Replace function =Replace(Fields!Info.Value, " ","") gets me almost there. Now I should be able to use a Right, 10 function to return my desired value. Is it possible to combine these two funtions together?
I'm moving data from one database to another (INSERT INTO ... SELECT ... FROM ....) and am encountering this error:
Msg 8114, Level 16, State 5, Line 6 Error converting data type varchar to numeric.
My problem is that Line 6 is:
set @brn_pk = '0D4BDE66347C440F'
so that is obviously not the problem and my query has almost 200 columns. I can go through one by one and compare what column is int in my destination table and what is varchar in my source tables, but that could take quite a while. How I can work out what column is causing the problem?
I need create a field to store tax rate. I need only 2 decimal points. I defined the field as decimal, precision=5 and scale=2. Does it mean that it can hold value from 0.00 to 999.99?
I am currently trying to find a way in which I can determine if a column in a Select clause is Japanese. The column currently supports English and Japanese Kanjis and other kanas. Is there a way to determine if this column is not English or if it is Japanese without physically looking at it.?
I need to determine if a value for a group of rows is the same or different and I am not sure where to begin. I am fairly new to writing T-Sql code. I am working with SQL Server 2005. This is a work assignment; I am not a student.
I have two tables: One for Course and another for CourseDays. As the Course table implies, it lists courses for a school. The CourseDays tables has a row for each day a course is held. For instance, one course maybe held on Monday, Wednesday, and Friday, so there would be three rows, one row for each day. A given course could be held in a different room for each day. I am trying to write a query that returns one row for each course, and if the room number is the same for each day the class is held, return that room number in the row, else return 'Various'.
Course table: CourseID, Desc 1 English 2 History 3 Science
CourseDays table: CourseID, Day, RoomID 1 M 320 1 W 445 1 F 680 2 T 123 2 Th 123 3 M 514 3 T 514 3 W 521 3 Th 901 3 F 521
Expected results: CourseID, Desc, RoomID 1 English Various 2 History 123 3 Science Various
I simplified the example, as there are about 30 columns in the table and about half a million rows.
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = 0,
bControlRiskIsAffirmed = 0,
bCombinedRiskIsAffirmed = 0,
bApproachTypeIsAffirmed = 0,
bCommentsIsAffirmed = 0
FROM EngagementAuditAreas WITH(NOLOCK) ...
And what I need is to conditionalize the values of the "IsAffirmed" fields by looking at their corresponding "num" fields. Something like this (which doesn't work).
UPDATE EngagementAuditAreas
SET numDeterminationLevelTypeId = parent.numDeterminationLevelTypeId,
numInherentRiskID = parent.numInherentRiskID,
numControlRiskID = parent.numControlRiskID,
numCombinedRiskID = parent.numCombinedRiskID,
numApproachTypeId = parent.numApproachTypeId,
bInherentRiskIsAffirmed = (numInherentRiskID IS NULL),
bControlRiskIsAffirmed = (numControlRiskID IS NULL),
bCombinedRiskIsAffirmed = (numCombinedRiskID IS NULL),
bApproachTypeIsAffirmed = (numApproachTypeID IS NULL),
bCommentsIsAffirmed = (parent.txtComments IS NULL)
Hello, everyone! What are the precision & the scale values in the numeric field for?(as also in int, etc).I need to have a field that is exactly 6 digits in length. However , when I enter the value , in the length column , it defaults to either 5 or 9 , depending on the precision values. Also when I enter the data , that field accepts not only 9(defined with precision of 10), but more than that, till about 15 digits!!…I think I am not clear on the use of precision…what do I need to define the field as so it accepts only 6 digits? Please enlighten me . Thanks in advance!

Hi all,I've set up a page with a gridview, and I'm trying to create a query based on three parameters and to display all records when the page loads.I have created the first two parameters no problem, but I'm having problems with the last one.The parameter is to be populated by a dropdownlist, where the selectedvalue is numeric. I have done a search and found that I can't use the '%' wildcard as it is for a string data type.I have read somewhere that to get around this I can use the CHAR() function to convert to a character, I have tried this without success.When creating the ControlParameter the datatype gets set to string, which I think is not working becuase the input has to be an integer for it to conver to char, am I right?This is the query, and it is the @Application parameter that I'm having this problem with. SELECT dbo.Issue.IssueID, dbo.Issue.ReportedBy, dbo.Issue.ShortDescription, dbo.Issue.DateReported, dbo.Issue.Status, dbo.Priority.Description AS Priority, dbo.Application.Application FROM dbo.Issue INNER JOIN dbo.Priority ON dbo.Issue.Priority = dbo.Priority.PriorityCode INNER JOIN dbo.Application ON dbo.Issue.Application = dbo.Application.ApplicationID WHERE (dbo.Issue.Status LIKE '%' + @Status) AND (dbo.Issue.AssignedTo = @AssignedTo) AND (CHAR(dbo.Application.ApplicationID) LIKE '%' + @Application) ORDER BY dbo.Priority.PriorityCodeHas anyone managed to do this another way?Thanks

I have a numeric data field called Price and this has a value of 0.000 in the db. when i create a package to extract this data to a flat file, the value is displayed as .000 what should i do to make it appear as 0.000 in the flat file.
I tried using a derived column expression where i check if the db value is 0.000 and display it as a string "0.000". this works fine if the OLEDB source is a sql command but fails if the OLEDB source is a sql command from variable.
How to get the max length of numeric field in a DataSet? I have a DataSet bound to an Access database. Is it possible to get the maximum length of numeric field of a table in the DataSet? Many fields in the database tables have maximum length values set in ...
I have several tables a varbinary column in a database. They have names like CSB_BLOB or OBJECT_BLOB. Now I am having intermittent success with getting the data out.
For example this query returns readable text from this data.
0x46726F6D3A20226465616E6E6167726.....etc --data as stored in the column
SELECT CAST(CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM OBJECT_BLOB
However this column has the following query results.
0x0001000000FFFFFFFF01000000000000000C....etc. --data as stored in column
--this query returns empty result
SELECT (CSB_BLOB AS VARCHAR(MAX)) AS 'Message' FROM CSB_STATUS_LOG
--this query returns no change???
SELECT CONVERT(VARCHAR(MAX), CONVERT(VARBINARY(MAX), CSB_BLOB, 2), 2) FROM CSB_STATUS_LOG 0001000000FFFFFFFF01000000000000000C....etc
Obviously there is a difference between the two but I am not educated enough to interpret this difference. What do I need to learn / read so I can look at the data in one of these BLOB columns and know how to convert it to something meaningful?
Something like:
1. Try to cast as varchar to see if it is text. 2. Turn into a byte array and see if it is a jpg 3. Turn into a byte array and see if it is a pdf 4. Convert it to hex and then cast as varchar 5. etc....
