GetDatabaseLong()
语法
Result = GetDatabaseLong(#Database, Column)概要
Returns the content of the specified #Database column as an integer number. This command is only valid after a successful FirstDatabaseRow(), PreviousDatabaseRow() or NextDatabaseRow().
参数
#Database The database to use. Column The column to use. DatabaseColumnIndex() is available to get the index of a named column.
返回值
Returns the content of the column as an integer 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.
