Specifies the maximum length of a text field that DB-Library™ or CT-Library returns when you include the text field in a SQL SELECT statement.
You can set the DBTextLimit parameter if you want to include a long text string in a DataWindow object without treating the text as a binary large object (blob) datatype.

Parameter |
Description |
|---|---|
value |
The maximum length in bytes of a text field that DB-Library or CT-Library returns when you include the text field in a SQL SELECT statement. The range of valid values is from 0 bytes to 32,763 bytes. When you set DBTextLimit to 0, DB-Library or CT-Library returns the maximum length text field. |
The default value for DBTextLimit is the default specified by SQL Server for the DBTEXTLIMIT DB-Library or CS_TEXTLIMIT CT-Library connection property (see your SQL Server documentation).
The text field length that DB-Library or CT-Library returns is the lesser of the DBTextLimit value and the setting for the SQL Server 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
SYC interface), or Maximum Length of Long VarChar box (when using
the DirectConnect interface) on the Syntax tab in the Database Profile
Setup dialog box.
Application Type the following in code:
SQLCA.DbParameter = "DBTextLimit='32000'"
