求SQL语句 创建存储过程,根使用游标计算本科及以上学历

以下是求SQL语句创建存储过程，使用游标计算本科及以上学历的示例：

CREATE PROCEDURE calculate_higher_edu_count
AS
BEGIN
    DECLARE @edu_level VARCHAR(20);
    DECLARE @count INT = 0;
    
    -- Declare cursor to loop through education levels
    DECLARE edu_cursor CURSOR FOR 
        SELECT education_level FROM education_table;
    
    OPEN edu_cursor;
    
    FETCH NEXT FROM edu_cursor INTO @edu_level;
    
    -- Loop through education levels
    WHILE @@FETCH_STATUS = 0
    BEGIN
        -- Check if education level is higher than or equal to undergraduate
        IF @edu_level IN ('Undergraduate', 'Master', 'Doctorate')
        BEGIN
            SET @count = @count + 1;
        END
        
        FETCH NEXT FROM edu_cursor INTO @edu_level;
    END
    
    CLOSE edu_cursor;
    DEALLOCATE edu_cursor;
    
    -- Output count of higher education levels
    SELECT @count AS higher_edu_count;
END

该存储过程中，先声明了一个游标 `edu_cursor`，用于循环遍历 `education_table` 表中的不同学历水平。然后在循环内部，使用条件判断语句计算出本科及以上学历的人数。最后输出计算结果。

注意，此例仅是示例，实际应用中需要根据具体情况进行修改和优化。
