Specifies the maximum length of a text field that is returned when you include the text field in a SQL SELECT statement.

Parameter |
Description |
|---|---|
value |
The maximum length in bytes of a text field that is returned when you include the text field in a SQL SELECT statement. The range of valid values is from 0 bytes to 2 GB. When you set DBTextLimit to 0, the server returns the maximum length text field. |
The default value for DBTextLimit is the default specified for the DBTEXTLIMIT DB-Library or CS_TEXTLIMIT CT-Library connection property.
The text field length that DB-Library or CT-Library returns is the lesser of the DBTextLimit value and the setting for the global variable TEXTSIZE.
If the setting for TEXTSIZE is less than the value you specify for DBTextLimit, DB-Library or CT-Library returns the TEXTSIZE value.
To have DB-Library or CT-Library return a text field that is up to 32,000 bytes long when you include the text field in a SQL SELECT statement:
Database profile Type 32000 in the Text
Limit in SQL box (when using the
ASE, or SYC, or SYJ interface), or Maximum Length of Long VarChar box
(when using the DirectConnect interface) on the Syntax page in the Database
Profile Setup dialog box.
Application Type the following in code:
SQLCA.DBParm="DBTextLimit='32000'"
