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

|
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. |
Default value
The default value for DBTextLimit is the default specified for the DBTEXTLIMIT DB-Library or CS_TEXTLIMIT CT-Library connection property.
Usage
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.
Examples
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 interface) on the Syntax page in the Database Profile Setup dialog box.
-
Application
Type the following in code:
SQLCA.DBParm="DBTextLimit='32000'"
