<Result>: Character string

Binary memo.

<Query name>: Character string

Name of the query created and executed with SQLExec, or executed with SQLExecWDR.

<Column number>: Integer

Number of the memo column to retrieve. This column corresponds to a query column (and not to a table column).

Remarks

Current row in the query

SQLFetch sets the position on the current row.

Query columns

To read columns other than Memo columns, use SQLGetCol.

Using a binary memo

The binary memo read by SQLGetMemo can be:

Played by Sound if the binary memo is a .WAV file.
Displayed in an Image control if the binary memo is in BMP format.
Stored in a file by HExtractMemo.
