Question

我有这个：

SELECT * FROM Person WHERE Age > 5

有没有办法使插入查询成为结果？

结果应如下所示：

INSERT INTO MyTable VALUES (.......)

谢谢

Answer 1

您在寻找INSERT . . . SELECT：

INSERT INTO mytable ( . . . )  -- list the columns here
    SELECT *   -- you should list the columns here too
    FROM Person
    WHERE Age > 5;

或者仅创建表，使用INTO：

SELECT p.*
INTO mytable
FROM Person p
WHERE Age > 5;

以下是一个脚本，该脚本迭代引发当前数据库并为其中的每个表创建一个SELECT INTO查询。您可以过滤查询以迭代引发所需的表或列，也可以将EXEC(@selectQuery)替换为Print @selectQuery以仅获取查询而不执行查询。

DECLARE @selectQuery NVARCHAR(MAX);
DECLARE @tableSchemaName NVARCHAR(MAX);
DECLARE @tableName NVARCHAR(MAX);

DECLARE @schemaId INT;

DECLARE C CURSOR FAST_FORWARD FOR(
SELECT schemas.schema_id,
       sys.schemas.name,
       sys.tables.name
FROM sys.tables
    INNER JOIN sys.schemas
        ON schemas.schema_id = TABLES.schema_id);
OPEN C;
FETCH NEXT FROM C
INTO @schemaId,
     @tableSchemaName,
     @tableName;
WHILE @@FETCH_STATUS = 0
BEGIN

    DECLARE @columns NVARCHAR(MAX);

    SELECT @columns = STRING_AGG(name, ',')
    FROM sys.columns
    WHERE object_id =
    (
        SELECT object_id
        FROM sys.tables
        WHERE name = @tableName
              AND schema_id = @schemaId
    );

    SET @selectQuery
        = N'SELECT ' + @columns + N' INTO ' + @tableSchemaName + N'.' + @tableName + N'2' + N' FROM '
          + @tableSchemaName + N'.' + @tableName;

    EXEC (@selectQuery);
    FETCH NEXT FROM C
    INTO @schemaId,
         @tableSchemaName,
         @tableName;
END;
CLOSE C;
DEALLOCATE C;
