运行时错误'；13'；：SQL代码中的类型不匹配

我在VBA中的部分SQL代码存在“运行时错误”13:类型不匹配

错误所指的代码是：

SQL = SQL & "   (select unique sv.gps_planshpdate from oes_delsegview sv, oes_opos op, oes_oposdelseg ds, oes_nrbom nb, ncf_comppart cp where cp.item_part_no = pd.part_no and nb.c_catnr = cp.catnr and nb.c_prodtyp = cp.prodtyp and nb.c_packtyp = cp.packtyp and nb.c_vernr = cp.vernr " & _
SQL = SQL & "       and sv.ordnr = ds.ordnr and sv.posnr = ds.posnr and sv.catnr = nb.p_catnr and sv.prodtyp = nb.p_prodtyp and sv.packtyp = nb.p_packtyp and op.ordnr = ds.ordnr and op.posnr = ds.posnr and op.catnr = nb.p_catnr and op.prodtyp = nb.p_prodtyp and op.packtyp = nb.p_packtyp " & _
SQL = SQL & "       and op.vernr = nb.p_vernr and nb.active = 'Y' and op.ol_typ in ('XX','CO') and sv.gps_planshpdate = " & _
SQL = SQL & "           (select max(sv1.gps_planshpdate) from oes_delsegview sv1, oes_opos op1, oes_oposdelseg ds1, oes_nrbom nb1, ncf_comppart cp1 where cp1.item_part_no = cp.item_part_no and nb1.c_catnr = cp1.catnr " & _

你知道如何在没有“类型不匹配”错误的情况下运行这段代码吗

谢谢

当我计算表达式时，它返回

FALSE

，这肯定是导致不匹配错误的原因，因为SQL需要字符串查询

问题在于您原来的连接方法，它错误地组合了两件事

如果您想这样做：

Sql = Sql & " some expression"
Sql = Sql & " some other expression"
'Etc.

注意，在上面的例子中，我没有像你一样继续这一行：

Sql = Sql & " some expression" & _
Sql = Sql & " some other expression" 

这将引起一个错误。因此，想象一下：

Sql = Sql & " A " & Sql = Sql & " B "

或：

由于此表达式的逻辑计算结果为

False

：此赋值语句的右侧是一个等价语句，并且由于等价语句中的两个表达式不相等，因此只能返回

False

我没有对您的查询表达式进行任何更改，只是纠正了对行连续字符的误用：

Dim SQL As String

当我计算该表达式时，

SQL

返回一个布尔值，

FALSE

。修复字符串连接，使其计算为查询语句，而不是布尔值。当然。。。现在说的很有道理。。。非常感谢。
