value |
The maximum length in bytes of text or large value datatypes returned when you include them in a DataWindow. The DataWindow can be created by a procedure. The range of valid values is from 10,000 bytes to 1,000,000 bytes. |
Default value
PBMaxTextSize=32767
Usage
The SQL Native Client OLE DB Provider for SQL Server automatically sets the SQL Server TEXTSIZE property to 2147483647 when connecting. The size of data fetched depends on the PBMaxTextSize parameter. If a result set includes a large value type, the blocking factor will be set to 1.
Examples
To have SQLServer return text or large datatypes that are up to 48,000 bytes long when you include them in a SQL SELECT statement:
-
Database profile
Type 48000 in the Maximum String Size in DataWindow box on the Transaction page in the Database Profile Setup dialog box.
-
Application
Type the following in code:
SQLCA.DBParm="PBMaxTextSize='48000'
