SQL存储过程实现分页查询

CREATE PROC myx_prPageRecordset
@queryStr nvarchar(1000), 
@keyField nvarchar (200), 
@pageSize int, 
@pageNumber int 
AS
BEGIN
DECLARE @sqlText AS nvarchar(4000)
DECLARE @sqlTable AS nvarchar(4000)
SET @sqlTable = 'SELECT TOP ' + CAST((@pageNumber + 1) * @pageSize AS varchar(30)) + ' ' + @queryStr
SET @sqlText =
'SELECT TOP ' + CAST(@pageSize AS varchar(30)) + ' * ' + 
'FROM (' + @sqlTable + ') AS tableA ' +
'WHERE ' + @keyField + ' NOT IN(SELECT TOP ' +
CAST(@pageNumber * @pageSize AS varchar(30)) + ' ' + @keyField + 
' FROM (' + @sqlTable + ') AS tableB)'
EXEC (@sqlText)
END
