with PB2017, SQL Server 2017, ODBC 13: selected varchar(max)-values will be truncated to 32K, whereas SNC works fine. I tried embedded sql (dynamic cursor) and datawindows.

Is there some datawindow parameter I can set appropriately?

Thanks for some advice.

there is also a connection parm of the same name, so it appears to control things the same way?

SQLCA.DBParm="PBMaxTextSize='48000'

the documentation says that it is only for SNC oledb, however i think some of the connection parm docs are often out of date.

 

i hate having to use ini files for these types of runtime parms.  windows security can prevent the ini file from being copied, and then you have a bunch of versions in users directories.

Mike, thanks for your hint.

But I tried this one already this morning and it didn't work, alas.



Hope that I don't have to copy the ini file into the user dir. Doesn't it suffice to provide it in the program folder on the central file server?

Edit pbodb170.ini and find the Microsoft SQL Server section. Change PBMaxTextSize to a larger number, 1,048,576‬ (1MB) for example.

[Microsoft SQL Server]
PBCatalogOwner='dbo'
PBSystemOwner='sys'
PBSyntax='MS_SQLSERVER_SYNTAX'
PBDateTime='MSSQLSERVER_DATETIME'
PBFunctions='MSSQL_FUNCTIONS'
PBSpecialDataTypes='SYBASE_SPECIALDATATYPES'
PBObjectIDs='YES'
PBMaxBlobSize='32767'
PBMaxTextSize='32767'
PBDWDynamic='NO'
PBPrimaryKeyName='YES'
Block=1
SQLSrvrTSPrefix='0x'
PBUseProcOwner='YES'
PBDefaultValues='USER,SYSTEM_USER,USER_ID(),HOST_ID(),HOST_NAME(),DB_ID(),DB_NAME(),CURRENT_TIMESTAMP,NULL'
PBDefaultCreate='YES'
PBDefaultAlter='NO'
PBDefaultExpressions='YES'

Roland, thank you very much. You made the rest of my day.

I already knew this PBMaxTextSize parameter by I thought it will only control the SQLServer Text type (and thus I used it for Selectblob).

Besides, I spent nearly an hour to find the correct pbodb170.ini (..users\appdata\local...).



Regards, Peter

Mike is right, there is also a DBParm for this setting.
