データ型nvarcharをfloatに変換するSQL INSERT INTO SELECTエラー

Question

現在、あるテーブルからデータを取り出し、いくつかの制約に基づいて別のテーブルにデータを挿入しようとしています。 私は、スクリプトを実行すると残念ながら、私は次のエラーを取得：

error converting data type nvarchar to float

をし、私はこの問題を解決するために、クエリを変更することができますかわからないんです。ソーステーブルと宛先テーブルの両方にはすべてのフィールドがnvarchar(255)となっています。私は何をすべきかよく分かりません。

次のようにSQLクエリは次のとおりです。

Insert into Database.dbo.ML_Records ([AccountNumber] 
    ,[House Number]

Answer 1

[CAT Status]行の1文字のように見えるので、sqlのキャスト時にエラーが発生します。 [CATステータス]変数をすべて確認できますか？

Answer 2

ルックをいただければ幸いです文字列。クエリの他の場所でその列への他の参照に基づいて、数値データ型を持つように見えます。数値データ型をconcatenateしようとすると、 "+"記号を使用すると、SQL Serverは数学を行うと考え、すべてを数値に変換しようとします。
