| In Access when you have a ‘LookUp’ column in a table, it literally shows the actual value from the other table instead of the primary key value of that particular table.Similar to a CBO, where you assign your DisplayMember value and ValueMember value… this is being used in a DataGridView from a dataset(s) in this particular case. The ValueMember (primary key) of the other table is inserted into the column of your current tableI need to compare two fields of similar SELECT statements using a UNION statement; but first I need to convert the value of the one field that holds the primary key value to the ‘DisplayMember’ value so I can later compare by or sort by a valid number or simply not the primary key values of Table2.Select Table1.Table1Id, Table1.Column1Table1.Column1 value is the primary key value chosen off of Table2, Table2ID.Table2Table2IDNumberScaleHow do I so this?*Thanks* |
