这是一个 SQL 查询语句，它从表格 formtable_main_43 和 formtable_main_43_dt1 中获取数据，并使用内部联接将它们组合起来。查询结果包括 t1 表格中的一些列，以及一个采购单价列。但是，查询语句提示了一个错误：不能对文本、ntext 和 image 数据类型进行比较或排序，除非使用 IS NULL 或 LIKE 运算符。这可能是因为查询中涉及了这些数据类型的列，但没有使用适当的运算符来处理它们。

如果想要在查询结果中展示名为‘htwj’的text字段，需要在SELECT语句中添加该字段，并在GROUP BY语句中同样添加该字段。具体的查询语句如下：

SELECT t1.id, t1.[requestId] AS t1_requestId, t1.[gf] AS '供方', t1.[htmc] AS '合同名称', t1.[htbh] AS '合同编号', t1.[sjbh] AS '编号', t1.[qdrq] AS '签订日期', t1.[qsrq] AS '起始日期', t1.[jzrq] AS '截止日期', t1.[zje] AS '总金额', t1.[zds] AS '总吨数', t1.[rksj] AS '入库时间', t1.[chpt] AS '撮合平台', t1.[qsfs] AS '签署方式', t1.[gfjc] AS '供方简称', t1.[cclx] AS '持仓类型', t1.[htwj] AS '合同文件', STUFF( ( SELECT ',' + CONVERT ( VARCHAR, CASE WHEN ISNUMERIC( REPLACE( t2.hsdj, ',', '' ) ) = 1 THEN CAST ( REPLACE( t2.hsdj, ',', '' ) AS FLOAT ) END ) FROM formtable_main_43_dt1 t2 WHERE t1.id = t2.mainid FOR XML PATH ( '' ) ), 1, 1, '' ) AS '采购单价' FROM formtable_main_43 t1 INNER JOIN formtable_main_43_dt1 t2 ON t1.id = t2.mainid GROUP BY t1.id, t1.[requestId] , t1.[gf] , t1.[htmc] , t1.[htbh] , t1.[sjbh] , t1.[qdrq], t1.[qsrq], t1.[jzrq] , t1.[zje] , t1.[zds] , t1.[rksj] , t1.[chpt] , t1.[qsfs], t1.[gfjc] , t1.[cclx], t1.[htwj];

请注意，这里假设‘htwj’字段确实存在且为text类型。如果该字段不存在或者类型不是text，查询语句需要做出相应的修改。

SELECT t1.id, t1.[requestId] AS t1_requestId, t1.[gf] AS '供方', t1.[htmc] AS '合同名称', t1.[htbh] AS '合同编号', t1.[sjbh] AS '编号', t1.[qdrq] AS '签订日期', t1.[qsrq] AS '起始日期', t1.[jzrq] AS '截止日期', t1.[zje] AS '总金额', t1.[zds] AS '总吨数', t1.[rksj] AS '入库时间', t1.[chpt] AS '撮合平台', t1.[htwj] AS '合同文件', t1.[qsfs] AS '签署方式', t1.[gfjc] AS '供方简称', t1.[cclx] AS '持仓类型' STUFF( ( SELECT ',' + CONVERT (VARCHAR, CASE WHEN ISNUMERIC(REPLACE(t2.hsdj, ',', '')) = 1 THEN CAST(REPLACE(t2.hsdj, ',', '') AS FLOAT) END ) FROM formtable_main_43_dt1 t2 WHERE t1.id = t2.mainid FOR XML PATH('') ), 1, 1, '' ) AS MergedValues FROM formtable_main_43 t1 INNER JOIN formtable_main_43_dt1 t2 ON t1.id = t2.mainid GROUP BY t1.id, t1.[requestId] AS t1_requestId, t1.[gf] AS '供方', t1.[htmc] AS '合同名称', t1.[htbh] AS '合同编号', t1.[sjbh] AS '编号', t1.[qdrq] AS '签订日期', t1.[qsrq] AS '起始日期', t1.[jzrq] AS '截止日期', t1.[zje] AS '总金额', t1.[zds] AS '总吨数', t1.[rksj] AS '入库时间', t1.[chpt] AS '撮合平台', t1.[htwj] AS '合同文件', t1.[qsfs] AS '签署方式', t1.[gfjc] AS '供方简称', t1.[cclx] AS '持仓类型' ，提示“STUFF”附近有语法错误。 (102) [42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]关键字 'FOR' 附近有语法错误

您需要在 STUFF 函数的第一个参数和第二个参数之间添加一个逗号，用于分隔这两个参数。同时，您需要为 STUFF 函数指定一个别名，否则会报错。请尝试使用以下 SQL 查询语句：

SELECT t1.id, 		
        t1.[requestId] AS t1_requestId, 		
        t1.[gf] AS '供方', 		
        t1.[htmc] AS '合同名称', 		
        t1.[htbh] AS '合同编号', 		
        t1.[sjbh] AS '编号', 		
        t1.[qdrq] AS '签订日期', 		
        t1.[qsrq] AS '起始日期', 		
        t1.[jzrq] AS '截止日期', 		
        t1.[zje] AS '总金额', 		
        t1.[zds] AS '总吨数', 		
        t1.[rksj] AS '入库时间', 		
        t1.[chpt] AS '撮合平台', 		
        t1.[htwj] AS '合同文件', 		
        t1.[qsfs] AS '签署方式', 		
        t1.[gfjc] AS '供方简称', 		
        t1.[cclx] AS '持仓类型',     
        STUFF(
            (
                SELECT ',' + CONVERT (VARCHAR,
                    CASE 
                        WHEN ISNUMERIC(REPLACE(t2.hsdj, ',', '')) = 1 THEN 
                            CAST(REPLACE(t2.hsdj, ',', '') AS FLOAT) 
                    END
                ) 
                FROM formtable_main_43_dt1 t2 
                WHERE t1.id = t2.mainid 
                FOR XML PATH('')
            ), 1, 1, ''
        ) AS MergedValues 
FROM formtable_main_43 t1 
INNER JOIN formtable_main_43_dt1 t2 ON t1.id = t2.mainid 
GROUP BY t1.id, t1.[requestId], t1.[gf], t1.[htmc], t1.[htbh], t1.[sjbh], t1.[qdrq], t1.[qsrq], t1.[jzrq], t1.[zje], t1.[zds], t1.[rksj], t1.[chpt], t1.[htwj], t1.[qsfs], t1.[gfjc], t1.[cclx], MergedValues;

请注意，使用 GROUP BY 时需要指定所有 SELECT 字段的列名，这些列名需要与 SELECT 子句中的列名一致。
