You can specify the OpenESQL preprocessor and its directive options using any of the following methods:
- In your
Visual COBOL Project
- Before compiling from within
Visual COBOL:
- Open your project properties and
click the
SQL tab.
- From the
ESQL Preprocessor drop-down list, select
OpenESQL.
- Click
Add; then click
DBMAN on the list of directives.
- From the
Value drop-down list, select
ODBC or
ADO; then click
OK.
- To add another directive, select a directive from the
Available Directives list.
- If required, provide details using the controls under
Directive Details.
- Click
OK. The directive is added to the
SQL Directives field.
- Repeat this procedure to add additional directives.
- On the Command Line
- Use the SQL compiler directive, followed by the DBMAN option to specify the type of database access:
SQL(DBMAN=dbaType)
Where
dbaType is
ODBC or
ADO.
- In a Directives File
- You can include OpenESQL preprocessor directives in the
cobol.dir system-wide directives file, a user directives file, or both. See
System-wide Directives File, cobol.dir
and
User Directives File for details.
- Embedded in a Program
- You can also specify the OpenESQL preprocessor and compiler directive options on the program level by embedding a
$SET statement into the program itself starting in column 1 on the first line of the program:
$SET SQL(DBMAN=dbaType [SQLdirOpts])
Where
dbaType is
ODBC or
ADO, and
SQLdirOpts is one or more additional directive options.
Important: Use this method only when the program requires a preprocessor different from other programs in an application.
