Could not create procedure Error: Must declare the scalar variable "@TableName"

Question

CREATE PROCEDURE [dbo].[sp_DropMasks]
@TableName nvarchar(127)='',
@FieldName nvarchar(127)='',
@MaskFunction nvarchar(127)=''
AS 
BEGIN
    declare @ATableName nvarchar(127)=''
    declare @AFieldName nvarchar(127)=''
    declare @AMaskFunction nvarchar(127)=''
    declare @SqlStr nvarchar(max)=''
    DECLARE crs CURSOR Read_Only Fast_Forward FOR
        SELECT TOP 100 PERCENT
            TableName=tbl.name,
            ColumnName=c.name,
            c.masking_function
        FROM 
            sys.masked_columns AS c inner join 
            sys.tables AS tbl ON c.object_id = tbl.object_id
        WHERE 
            is_masked=1 and 
            tbl.name like '%'+@TableName+'%' and 
            c.name like '%'+@FieldName+'%' and 
            c.masking_function like '%'+@MaskFunction+'%'
    Open crs
    Fetch Next From crs INTO @ATableName,@AFieldName,@AMaskFunction
    WHILE @@FETCH_STATUS = 0
    BEGIN
        set @SqlStr = @SqlStr + 
                    ' ALTER TABLE ' + @ATableName +
                    ' ALTER COLUMN ' + @AFieldName + 
                    ' DROP MASKED ' 
        Fetch Next From crs INTO @ATableName,@AFieldName,@AMaskFunction
    END
    CLOSE crs
    DEALLOCATE crs
    if @SqlStr <> ''
        exec(@SqlStr)
END;

I cannot see the invalid syntax or the missing declaration.

The error is;

Msg 156, Level 15, State 1, Line 28 Incorrect syntax near the keyword 'PROCEDURE'.

我忘了在连接时始终关闭加密功能。
