GetDatabaseDouble()

Syntax

Result.d = GetDatabaseDouble(#Database, Column)

Returns the content of the specified database column as a double precision floating-point number. This command is only valid after a successful FirstDatabaseRow(), PreviousDatabaseRow() or NextDatabaseRow().

Parameters

#Database	The database to use.
Column	The column to use. DatabaseColumnIndex() is available to get the index of a named column.

Return value

Returns a double precision floating-point value.

Remarks

To determine the type of a column, DatabaseColumnType() can be used.

Note: This function can be called only once for each column. Therefore if this value needs to be used more than once, the data has to be stored in a variable, since all subsequent calls will return the wrong value. This is an ODBC limitation.
