データベースからデータを選択していて、その列に値が含まれていない場合、「空白」が出力されます。クエリを実行すると、以下のエラーが発生します。検索しようとしたが、私が持っている答えはうまくいかない。 数字のエラーです。

ERROR: invalid input syntax for type numeric: "" 
LINE 35: ,CASE WHEN npi.temp_member_number IS NULL THEN ''

私は例えば、あなたがテキストにnumericをキャストすることを行うために、1234または空の文字列 ``、ゼロではないようないくつかの番号をeuther見るであろうように、テキストではなく、整数を取得しようとしますその後、

ELSE npi.temp_member_number::text

あなたはどこE、wanter結果は...

は（すべてではないテキストフィールドに適用され得ます空の文字列である場合は NULL）
