I'm using this query to sum the values. The cost column is a float datatype and what could I differently do here to sum the cost. I'm unable to sum the cost.
Also is there any way I change the datatype to int for Cost column without losing the data.
select ID, MAX(Date) Date, SUM(Cost) Cost, MAX(Funding) Funding from Application
group by ID

View 4 Replies View RelatedHello,How do I change the datatype of a column in a CSV file. Preferably in the select statement (apparently Cast, Convert, & Replace functions don't work when selecting from a CSV). I have a page where users upload their CSV files to and then I use SQLBulkCopy to insert all the records into my sql table. The problem is with columns of money data. EX: "$2,000" >> 2000The CSV file interprets the "$2,000" as a string of text. How do I convert it to a decimal so I can insert it into my sql database?

Any help appreciated.
Hi guys,
Is there any way or method to CHANGE the DATATYPE of a column in a published table being used for transactional replication (MSSQL 2000), WITHOUT DROPPING THE SUBSCRIPTION ????
Im stuck in this mess and do have the option to drop the subscription, alter the table, create the subscription and rerun the snapshot or to recreate it by Manual Synchronisation either.
Can anyone help? Has anyone been across this dilemma before and have troubleshooted the problem? If yes, help is much appreciated.
MY PROBLEM:
~~~~~~~~~~~~~
'MyTable' is currently being published and has subscriptions to it. The PRIMARY KEY column 'id' has an Identity property as well. 'id' is of datatype smallint, however because of bad planning, i now need to change that datatype to an integer to support a larger range WITHOUT DROPPING SUBSCRIPTIONS.
I CANT DROP THE COLUMN EITHER AS IT IS BEING THE PRIMARY KEY COLUMN.
IS THERE ANY OTHER WAY I CAN DO TO ARCHIEVE MY GOAL? THANKYOU.
Hi,
How do we find the "column name" and "data type" of all the columns in a table. Assuming that I know the Table name or Table Object ID. I am using Microsoft SQL Server 2000.
Thanks

I am trying to make the following update: All the columns are fine except for the 'name' column. datatype for 'name' column in the target table is varchar(30) and the datatype for 'name' in the sourcetable is varchar(40), I cannot change the datatype of the column 'name' to varchar(40) because I am told it may affect performance. what I want to do is just update the first 'name' column of the target table by the first 30 characters of the source table column 'name'
I am using the following query, is it possible to do it or are there any other ways I can update the column without changing the datatype?
MERGE INTO [S].[dbo].[AF_Copy] AS TargetTable
USING (SELECT source_code, name, addr1, city, zip FROM
[D].[D_TEST].[dbo].[SO_Copy]) AS SourceTable
ON ([TargetTable].[Code] = [SourceTable].[source_code])
[code]...

Hello. I using a simply SELECT statement to retrieve some data from aSQL SERVER via an ODBC connection. I had to go from VARCHAR to TEXTbecause the amount of data. Anyway, my SQL statements worked just finewhen I was using VARCHAR, but now since I am using TEXT, I am onlyreceiving part of the content back. Do I have to do some sort ofspecial Casting or something if I want to get all the content back?It's over 8,000 characters. Thank you very much. I have racking mybrain on this for a while.
View 8 Replies View RelatedHere is my expression in a derived component:
"Failed insert into PONL_WELL. WELL_NO=" + (DT_WSTR,10)PROP_NO
PROP_NO comes from ms sql server , and the derived component datatype for this column is DT_WSTR.
The destination will be ms sql server, and i have a data conversion after the derived component to cast from DT_WSTR to DT_STR.
However, the derived component failed everytime giving me
Error: 0xC0049064 at Load Ponl_Well, Derived Column [1342]: An error occurred while attempting to perform a type cast.
Anyone know how i can eliminate the data conversion component and just do my string and column concatenation in the derived column and have it output as DT_STR?
1) it is in the same filegroup as the rest of the table?
2) it is stored in a filegroup separately from the rest of the table (I think this is allowed)?

I am populating a rad grid with foreign language data. I have set the sql server 2005 Database table column to nvarchar.

I need to alter the datatype of a column from smallint to decimal (14,2) but the column was originally created with the following:
alter my_table
add col_1 smallintNot Null
constraint df_my_table__col_1 default 0
go
I want to keep the default constraint, but i get errors when I try to do the following to alter the datatype:
alter table my_table
alter column col_1 decimal(14,2)Not Null
go
Do I need to drop the constraint before I alter the column and then rebuild the constraint? An example would be helpful.
Thx
Hi,
When i try to retirve the datatype of a variant column using SQLColAttribute, the datatype comes back as SQL_BINARY(-2) instead of a CHAR based type. To reproduce the problem, add extended property 'MS_Description' to either a column or a table. Assign a text value to the property.
Execute the following query and verify. SELECT value FROM sys.extended_properties WHERE name = 'MS_Description'
I'm using SQL Server 2005 sp 2 with Visual Studio 2005.
Here is the code i use -
Code Block
SQLHENV m_SQLEnvironment;
SQLHDBC m_SQLConnection;
SQLHSTMT m_SQLStatement;
SQLRETURN iReturn;
CString sConnectionString = _T("DRIVER={SQL Native Client};SERVER=YourServer;DATABASE=YourDatabase;Trusted_Connection=yes;");
CString sQuery = _T("SELECT value FROM sys.extended_properties WHERE name = 'MS_Description'") ;
iReturn = SQLAllocHandle( SQL_HANDLE_ENV,SQL_NULL_HANDLE,&m_SQLEnvironment);
iReturn = SQLSetEnvAttr(m_SQLEnvironment,SQL_ATTR_ODBC_VERSION,(SQLPOINTER) SQL_OV_ODBC3,0);
iReturn = SQLAllocHandle(SQL_HANDLE_DBC,m_SQLEnvironment,&m_SQLConnection);
iReturn = SQLAllocHandle(SQL_HANDLE_STMT, m_SQLConnection, &m_SQLStatement );
SQLCHAR szwOutputConnectionString[800];
SQLSMALLINT nOutputStringLength = 0;
SQLUSMALLINT nDriverCompletion = SQL_DRIVER_NOPROMPT;
iReturn = SQLDriverConnect( m_SQLConnection, m_hWnd, (SQLCHAR*)(LPCSTR)sConnectionString, SQL_NTS, szwOutputConnectionString, 800, &nOutputStringLength, nDriverCompletion );
iReturn = SQLAllocHandle( SQL_HANDLE_STMT,m_SQLConnection,&m_SQLStatement);
iReturn = SQLPrepare( m_SQLStatement, (SQLCHAR*)(LPCSTR)sQuery , SQL_NTS );
iReturn = SQLExecute( m_SQLStatement );
iReturn = SQLFetch( m_SQLStatement );
SQLINTEGER nType = 0;
SQLSMALLINT nDummyInt = 0;
//get the datatype of the variant
iReturn = SQLColAttribute( m_SQLStatement, (SQLUSMALLINT) 1, SQL_CA_SS_VARIANT_TYPE, NULL, NULL, &nDummyInt, &nType );
After the execution of SQLColAttribute, nType value is assigned a value of -2 (SQL_BINARY) instead of a CHAR based type. What am i doing wrong? Any help is appreciated.

Hi,
I have a trigger that fires on update, populating a varchar field [ExampleDate_Str] with the dd/mm/yy format of the inserted datetime field [ExampleDate]. It works, but I don't want to rewrite it for the thousands of datetime fields in hundreds of tables in my db. So I am looking for a way to do something like this in a trigger -
for each column in triggered tableset @ColName = (the column name)if datatype(@ColName) = datetimeset @ColName + "_Str" = convert(varchar(8),ExampleDate,3)next
Obviously the above doesn't work in SQL or indeed any other language yet invented - is it possible to make it so that it does, and if so, how? The main points are to read the column name into a variable, check the datatype, and modify the column named @ColName + "_Str".
Thanks...
which is to parse a create table script using Microsoft.SqlServer.TransactSql.ScriptDom namespace..I get a list of statements : StatementList SQLStatement = parser.ParseStatementList(StreamReader, out errors);then I cast a relevant statement to the CreateTableStatement type which gives me access to the ColumnDefinition class.
foreach (TSqlStatement T in SQLStatement.Statements)
{ if (T is CreateTableStatement) { CreateTableStatement TC= (CreateTableStatement)T}}
with foreach (ColumnDefinition CD in TC.Definition.ColumnDefinitions)
I am ready to loop through the columns so far so good. I can get to the column name using CD.ColumnIdetifier.Value, to the data type using CD.DataType.Name.BaseIdentifier.Value, but can't seem to get to the length definition. Meaning, I can get column1 , varchar; but I need column1, varchar(40). where do I get (40) from?I tried using ScriptTokenStream under C.DataType, but it seems to iterate through all tokens not just ones relevant to that fragment.
I have been fighting with this all day. If you can point me in the right direction I'd appreiciate it. I need to load about 500 jpg files into a table. The table has 3 columns an "ID", "Filename" which has the filename of the jpg in it already, but not the unc path, and a ("Photo" Image Datatype)column which is not populated yet. I need to store the Image file in the photo field so that I can run reports in reporting services and so on and so forth. I am not sure how to complete this task.

Hi, friend,
l've 2 variables A & B from source database which i used to calculate C with the following formula, i.e.
C = 100 * A/B
In case of B = 0 (DIV BY ZERO), C should be equal to -9999.
l've set the datatype for A & B are INT, C is FLOAT at targetting database.
So l used to derived column to calculate C as,
B == 0 ? -9999 : 100 * A/B
After l run the package, l realize that all my C is INTEGER rather than FLOAT.....it seems that SQL server has evaluate the wrong datatype for me....anyway to overcome this?
