Question

我需要sql脚本来检查，从数据库中有多少表有数据，有多少表是空的？

Answer 1

试试这个：

USE dbName
SELECT COUNT(*) from information_schema.tables 
WHERE table_type = 'base table'

Answer 2

AS @ James Z在评论中建议您可以使用SSMS中的标准报告 {strong>右键单击<{1}}实例

上的

报告 - ＆gt;标准报告 - ＆gt;表格的磁盘使用

请尝试以下方法......

CREATE PROCEDURE EmptyFullTableCounter AS
BEGIN
    DECLARE @fldNameValue VARCHAR( 64 );
    DECLARE @sqlStatementString varchar( 200 );

    DECLARE @loopIndex INT = 1;
    DECLARE @recordCount INT;

    DROP TABLE IF EXISTS tempTblTableNames;

    CREATE TABLE tempTblTableNames
    (
        fldName    VARCHAR( 64 ),
        fldCount   INT
    );

    INSERT INTO tempTblTableNames ( fldName,
                                    fldCount )
    SELECT table_name,
           0
    FROM INFORMATION_SCHEMA.TABLES
    WHERE table_type = 'BASE TABLE'
      AND table_catalog = 'UserAccessAccounts001'
      AND table_name != 'tempTblTableNames';

    SET @recordCount = ( SELECT COUNT( * )
                         FROM tempTblTableNames );

    WHILE @loopIndex <= @recordCount
        BEGIN
            SET @fldNameValue = ( SELECT fldName
                                  FROM ( SELECT fldName,
                                                ROW_NUMBER() OVER ( ORDER BY fldName ) AS recordNumber
                                         FROM ( SELECT fldName
                                                FROM tempTblTableNames
                                              ) AS fldNamesFinder
                                       ) AS fldNamesWithRowNumber
                                  WHERE recordNumber = @loopIndex );

            SET @sqlStatementString = 'UPDATE tempTblTableNames ' +
                                      'SET fldCount = ( SELECT COUNT( * ) ' +
                                      '                 FROM ' +
                                      @fldNameValue +
                                      ' ) ' +
                                      'WHERE fldName = ''' +
                                      @fldNameValue +
                                      ''';';

            EXEC ( @sqlStatementString );

            SET @loopIndex = @loopIndex + 1;
        END

    SELECT SUM( IIF( fldCount > 0, 1, 0 ) ) AS Haves,
           SUM( IIF( fldCount = 0, 1, 0 ) ) AS HaveNots
    FROM tempTblTableNames;

    DROP TABLE tempTblTableNames;
END

此过程首先创建一个表来保存每个表的名称，然后使用以下语句填充它...

INSERT INTO tempTblTableNames ( fldName,
                                fldCount )
SELECT table_name,
       0
FROM INFORMATION_SCHEMA.TABLES
WHERE table_type = 'BASE TABLE'
  AND table_catalog = 'UserAccessAccounts001'
  AND table_name != 'tempTblTableNames';

请注意，上述声明从我们的表格列表中排除了tempTblTableNames。

然后，该过程存储变量@recordCount中记录总数的计数。此值用作WHILE循环的标记值，该循环从tempTblTableNames中提取每个表名，并在其周围构建一个语句，该语句将更新tempTblTableNames中该表名的关联计数。然后执行该语句并迭代循环索引。

循环完成后，执行最终SELECT语句，将SUM()与IIF()结合使用，以计算具有记录的表的数量和不具有记录的表的数量有记录。
