SQL Server 2012 :: Join On Different Data Types
Jun 11, 2014
We have a query that joins column A int which is an int onto column B with contains only int's but was created as a varchar and can't be changed to an int at the moment.
Casting column a as a varchar in the ON of the join to left join seems to void the index altogether and the query just runs for every.
We are talking a few hundred million rows of data in each table.
Temp solution is select into a #Hash table as correct data type and index then use the #Hash table in the join.

I am trying to join two tables together, on the same field except they have different data types, see the properties below
Code:
TableCOLUMN_NAMEDATA_TYPECHARACTER MAXIMUM LENGTHCHARACTER OCTET LENGTHCHARACTER SET NAMECOLLATION NAME
1itemClassnvarchar 512 1024 UNICODE Latin1_General_CI_AI
2PGCode varchar 3 3 iso_1 Latin1_General_CI_AS
in the code for the join,
Code:
left join common.dbo.qryPRDGroupDets on CAST(qryData_GB1_ByColumn.itemclass as varchar(3)) = Cast(common.dbo.qryPRDGroupDets.PGCode as varchar(3))
I have tried using the CAST function on one side of the join then on both, to no avail...

Does sql server 2012 support varbinary data type for replication (Merge or transaction)?
And if so, is there a limitation of data size?

I have a requirement of creating nested tables in SQL server. how to create them. Just to give a background I am trying to move the RDBMS from oracle to SQL server.
Structure of tables is as follows. I have table 'Employees' with address as one of the column. I have one more table with columns Street, Town, Dist, State. When I query the table 'Employees' I should see the attribute name and values of all the columns in address table in address column.
Employees: with columns: ID, FirstName, LastName, dept, gender, dob, address
Address (Nested table): with columns : Street, Town, Dist, State
This was done in oracle using Nested tables and user defined data types. what is alternative for this in SQL server. How can I achive this requirement in SQL server.

Hi,
I´m exporting an ms-excel file, then I use a lookup transformation to get a field from a SQL Server 2005 table. The Lookup transformation editor, after selecting the table, shows a warning that says:
at least one mapping between a column from available input columns ans a column from available lookup columns must be defined on the columns page.
So I try to make a relationship in the Lookup transformation editor's column tab where I find the Available input columns and the available lookup columns but I get the following error:
The following columns cannot be mapped:
[Department, DEP_CLEGALCODE]
One or more columns do not have supported data types, or their data types do not match.
The field in SLQ Server is varchar(10) and the input field is a derived column transformation; I have tried different Data Types but I always have the same error.
The DataFlow is: ExcelSource --> Derived Column --> Lookup --> Flat file destination
thanks.

I have an SSIS package that pulls data from a MYSQL DB (Using RSSBus for Salesforce in SSIS to accomplish this). Most of the columns are loading properly, but I have many columns that I need to convert.
I have been using the Data Conversion dataflow task in SSIS to convert the rows.
I have 2 data conversions that work on most of the columns, but the DESCRIPTION column continues to return an error saying "Cannot convert between unicode and non-unicode types", regardless of what I choose on the Data Conversion task. So, basically I want to dump this column data into a SQL table with NVARCHAR datatypes. Here is what I am doing in my SSIS package...
1) Grab subset of data from SOURCE
2) Converts to TEXTSTREAM. (Data Conversion)
3) Converts to STRING. (Data Conversion)
4) Load Destination table. (OLE DB Destination)
I have also tried to simply convert the values to STRING, but that doesn't work either.
So, I have 2 Data Conversions working here that process most of the data correctly. What I can do to load the DESCRIPTION column?

I have created a common table expression. The first query is meant to select a particular months worth of data. The second query is meant to select the following months data but only for the subscribers (MSISDN's) that appeared in the first month.
The query returns result for month 1 but ignores the second month. If I remove the last inner join to the CTE (INNER JOIN Test_Table tt ON tt.MSISDN = B.SUBSCRIBER_NUMBER) then I get a full list for both months but obviously this isn't limited to those MSISDN's in the first month.
The second issue that I'm having is that I can't select a sample of say only a 1000 MSISDN's from the first month...
WITH Test_Table (Report_Month, MSISDN, SUB_SEGMENT)
AS
(
Select
R.Report_Month,
R.MSISDN,
DV.SUB_SEGMENT
[code]....

Will writes "I have an employees table, which gives all emp. ids. I have a second table, time_log with tasks each employee has logged:
empID date log_time duration etc
===================================
and a 3rd table - a pivot table with a single column named "i" containing consecutive integers from 0 - 1000
I need to know for each date in a series, e.g seven consecutive days, how much time each has logged. easy if everyone has logged a task for every day, but I need to include every day where they have not logged a task.
so, a cartesian join on all the dates in a series(produced using dateadd on p.i and the pivot table)
SELECT dateadd('d',p.i, #02/19/2007#), e.empID
FROM pivot1 p, employees e
WHERE i<no_dates
However I need to do a left join with time log where the date and employee ids are the same, and I have summed the durations for each date. The following query does this, but does not include dates and times where nothing has been logged.
SELECT empID, log_date, sum(duration)
FROM time_log
GROUP BY empEIN, log_date
GIVING, EVENTUALLY, ALL DATES AND EMPIDS AND THE TOTAL AMOUNT OF TIME THEY HAVE LOGGED FOR EACH DAY."

Hi,
I'm seeing confusing results coming back from a query and I want to make sure my joins are working as expected.
I have 3 tables, tbl_family, tbl_familyPhone, and tbl_phone. tbl_FamilyPhone is a linking table between families and phones that specifies if it's the primary number.
tbl_Family tbl_FamilyPhone tbl_Phone
--------------- ------------------------- ----------------
pk_FamilyID pk_FamilyPhoneID pk_phoneID
fName fk_FamilyID fk_TypeID
lName fk_PhoneID ...
... ...
So a family has many familyPhones and a phone has many family phones. I'm trying to get all the families and their home phone only, if they have one. I don't want families to duplicate and I don't want any left out. Here's what I've got
Code Snippet
select [whatever]
from tbl_family
LEFT OUTER JOIN tbl_familyphone on tbl_family.pk_familyid = tbl_Familyphone.fk_familyid
inner JOIN tbl_phone on tbl_familyphone.fk_phoneID = tbl_phone.pk_phoneid and tbl_phone.fk_phonetypeid = 'E6F1688E-015B-481D-8C41-DCC1FEA5D5AB'
My thinking is the inner join between tbl_Phone and tbl_FamilyPhone will cause any FamilyPhone record without a phone record to be left out (fk_phonetypeid is the id of a home phone). Though some FamilyPhone records may be left out, I will not lose any families because it is left outer joined to familyphone. Is this right? Because if I just do select count(*) from families I get 4517 records, but when running the query above with the joins, I get 4383 records.

I am trying to write a generic stored procedure to return the data type of a given col in a given table in any database.
I would like to place this sp in master.
input parms are @TableName sysname and @ColName sysname
ouput parm is @data_type varchar(128)
set @data_type=''
select @data_type = data_type from information_schema.columns where table_name = @TableName and column_name = @ColName
when debugging this I always get 0 rows (@data_type remains '')
I have a thought that I can add an input parm for the database, say @DbName sysname
But I am having trouble updating the select stmt to be something like
...from @DbName +'.' + information_schema.columns.
Any Ideas?
Thanks for your help.

SQL Server 2000, ASP.Net 1.1
I've been writing this stuff for a while, and can't seem to come to the
conclusion of how I should be retrieving data and assigning this data
to variables.
Since i'm using SQL Server, I'm convinced that I should be using the
datareaders GetSqlDouble (or whatever) function, but this would mean i
need my local variables to be one of the SQL types. The problem
with that is, that there will have to be lots of conversions done by me
to be able to use a SQL type in my application.
For instance, I have a class where i'm retrieving dates. In order
to retrieve them correctly (Null values included), I need to retrieve
them with GetSqlDateTime(), then when it comes time to display the date
in a table, i must first check for nulls, then convert to a
string. This seems to be very cumbersome. Would I be better
off just using GetDateTime(), and the .ToString method, and ignoring
Sql Types all together?
so, basically, how are you guys using your sql server data? with
the supplied sql types, and doing all of the post-processing work
manually? I feel like i'm having trouble conveying my
issue...hopefully someone knows what i mean....i'd just like some
direction to save trouble in the long run, since i feel like there's
got to be a better way...
Confused!
Thanks,
JJ

Is there a way to change the default data type in SQL Server? If I import a database into SQL Server it makes every non-numeric field a nvarchar field. Is there a way to change this so that these fields would be varchar or char by default? I cannot find any way to redo these as a batch/group update and have to modify every single field manually. Any insights greatly appreciated.

I trust you'll bear with an SQL Server newbie with what may seem a rather inane request. I am designing a web app in Web Designer 2005 Express with SQL Server Express. Unfortunately, I'm finding a little confusing with some of the data types when designing tables. I have tried to find information on the various Microsoft sites (general site, MSDN, here) and while I found one document that had a table comparing data types in different implementations of SQL, it wasn't at all helpful. Most of my confusion is with the various string and char types; the numeric types seem pretty straight forward for the most part. However, it might be helpful to know the difference between money and smallmoney/datetime and smalldatetime, particularly space/size information and formatting options (unless the latter is up to the interface). It would also be helpful to know which string/char types correspond to any counterparts they might have in, for instance, Access (with which I am already quite exprienced). Or any particular quirks or idiosyncracies they might have. I don't expect anyone to write a full tutorial, but if someone could point me in the direction of a good online doc, it would be most appreciated. You might well ask, why not use Access databases? I would answer...I like to learn new stuff!
Thanks much.

Hi,Can anybody tell me if it is possible to return a table data type (asopposed to a temporary table) from a stored procedure.I am currently studying for 70-229 using the Thomas Moore book but itdoesn't really make it clear, as the text suggests you can't returnthem but some of his sample questions suggest you can.I can't make it work in Query Analyser so I am assuming that you can'treturn them. Is that correct?Thanks in advance for any help,Simon.

Hi,
I´m building an aplication with VB.net and SQL Server 9, but in the future it will be compatible with PostgreSQL (by another developer), so my question is, if anyone knows what "data types" in SQL Server 9 i must use to maintain compatibility with PostgreSQL, so that when the time come for the conversion i don t have to chage the "Data Types" on each table.
Any help would be apreciated.

I have a simple Integration Services project and the problem is that decimal fields are importing as real (I'm loosing the digits behind the decimal point).
The project contains a data flow task importing a flat file (.csv) to an SQL Server destination. My .csv file has two decimal type fields. Example:
Field 1: 12345.67
Field 2: .123456
My database table that I'm importing to has two fields. The only way that I can get this data to import is to define the fields as "float" in both the text file and database table. I want the database table fields to be defined as decimal or numeric, not float:
Field 1: decimal(7,2)
Field 2: decimal(6,6)
When all fields are defined as decimal (in both the flat file and database file), I get the following results:
Field 1: 12345.00
Field 2: .000000
How does one import decimal data from a flat file (.csv)?
Thank you in advance!

I have two tables, INCIDENT and PEOPLE
INCIDENT has two fields, ID and Date
PEOPLE has three fields, INC_ID [foreign key to INCIDENT.ID], PersonIteration, Complaint
There is always only one incident, but there can be one or more people involved in each incident.
I'd like to retrieve incidents, but have it include information from all involved person on one line.
No matter how I have tried to join these tables, I am ending up with one record each for each person involved in an incident, like so
ID PersonIteration Complaint
1 1 Head
1 2 Neck
1 3 Shoulder
I would like to join in this fashion:
ID PersonIteration1 Complaint1 PersonIteration2 Complaint2
1 1 Head 2 Neck
Is there any way to do this?

I need to add a join in my select query depending upon a variable @LoggedUser. the Join is to be there if @loggedUser is 1 else i do not need it. Currently I am using two different queries one with join and one without it under If (@LoggedUser check).
the join is like -
JOIN (SELECT CAST(CONVERT(VARCHAR(8),Analyst_Effective_date , 1) AS DATETIME) Analyst_Effective_date
FROM Users us (NOLOCK) JOIN Primary_Analysts (NOLOCK)
ON User_Count_Id = Analyst_Id_fk
WHERE User_Count_Id in ((SELECT VALUE FROM dbo.fParseString(@Analyst, ',')) )) Ana
ON dep.Departure_Code = Ana.Primary_Analyst_Departure_Code_fk
)
Any way that the join can be added conditionally in the query so i do not have to write the whole code again for one join.

I have two tables tabA (cola1, cola2, cola3) and tabB(colb1, colb2, colb3, colb4) which I need to join on all 3 columns of table A.
Of the 3 columns in tabA, few can be NULL, in that case I want to check the joining condition for the rest of the columns, so its conditional joining. Let me rephrase what I am trying to acheive - I need to check if the columns in joining condition is NULL in my 1st table (tabA), If so I need to check the joining condition for the rest of the two columns, if 2nd column is again NULL, I need to check the joining condition on the third column.
What I am trying to do is as below. Its working, but is very slow when one of the tables is huge. Can I optimize it or rewrite in a better way ?
--- First Create two tables
Create table tabA
(cola1 nvarchar(100), cola2 nvarchar(100), cola3 nvarchar(100))
Insert into tabA values (NULL,'A1','A2')
Select * from tabA
create table tabB
