Remove Column Qualifiers

Attribute

RemoveColumnQualifiers (RCQ)

Purpose

Specifies whether the driver removes 3-part column qualifiers and replaces them with alias.column qualifiers. Microsoft Access executes a Select statement using this syntax when an index is specified on a linked table.

Valid Values

0 | 1

Behavior

If set to 1 (enabled) the driver removes 3-part column qualifiers and replaces them with alias.column qualifiers. Column qualifiers are Microsoft Access compatible in this setting.
If set to 0, the driver does not modify the request.

Notes

*When using the driver with Microsoft Access in creating a linked table, it is highly recommended that you do not specify an index. Specifying an index causes Access to execute a Select statement for each row, which results in very slow performance.

Default

0 (Disabled)
