我可以请求您帮助我将这个 {oj } SQL 语法转换为正常的连接语法吗？
SELECT
...
FROM
{oj (((((((((("VMPH" "VMPH" LEFT OUTER JOIN "VMPT" "VMPT" ON "VMPH"."NMPSTID"="VMPT"."NMPSTID")
LEFT OUTER JOIN "ARRTA" "ARRTA" ON "VMPH"."TXTERM"="ARRTA"."CODETERM")
LEFT OUTER JOIN "VMAGRE" "VMAGRE" ON "VMPH"."NMAGRE"="VMAGRE"."NMDOCID")
LEFT OUTER JOIN "VMDH" "VMDH" ON "VMPH"."NMDOCID"="VMDH"."NMDOCID")
LEFT OUTER JOIN "VMPTIT" "VMPTIT" ON ("VMPT"."NMPSTID"="VMPTIT"."NMPSTID") AND ("VMPT"."WDTRANNUM"="VMPTIT"."WDTRANNUM"))
LEFT OUTER JOIN "VMPTSV" "VMPTSV" ON ("VMPT"."NMPSTID"="VMPTSV"."NMPSTID") AND ("VMPT"."WDTRANNUM"="VMPTSV"."WDTRANNUM"))
LEFT OUTER JOIN "VMPTEQ" "VMPTEQ" ON ("VMPT"."NMPSTID"="VMPTEQ"."NMPSTID") AND ("VMPT"."WDTRANNUM"="VMPTEQ"."WDTRANNUM"))
LEFT OUTER JOIN "VMDTEQ" "VMDTEQ" ON ("VMPT"."NMDOCID"="VMDTEQ"."NMDOCID") AND ("VMPT"."WDDTTRNUM"="VMDTEQ"."WDTRANNUM"))
LEFT OUTER JOIN "VMMTRM" "VMMTRM" ON ("VMPTEQ"."TXEQUP"="VMMTRM"."TXEQUP") AND ("VMPTEQ"."TXMETER"="VMMTRM"."TXMETER"))
LEFT OUTER JOIN "VMEQUP" "VMEQUP" ON ("VMPTEQ"."TXEQUP"="VMEQUP"."TXEQUP"))
LEFT OUTER JOIN "VMSERV" "VMSERV" ON ("VMPTSV"."WDSERVTYPE"="VMSERV"."WDTYPE") AND ("VMPTSV"."TXSERV"="VMSERV"."TXSERV")}
我尝试删除括号和“oj”，但它不起作用。我尝试了下面这个，但效果不佳
SELECT
...
WHERE
"VMPH"."NMPSTID" = "VMPT"."NMPSTID"
AND "VMPH"."TXTERM" = "ARRTA"."CODETERM"
AND "VMPH"."NMAGRE" = "VMAGRE"."NMDOCID"
AND "VMPH"."NMDOCID" = "VMDH"."NMDOCID"
AND (("VMPT"."NMPSTID" = "VMPTIT"."NMPSTID") AND ("VMPT"."WDTRANNUM" = "VMPTIT"."WDTRANNUM"))
AND (("VMPT"."NMPSTID" = "VMPTSV"."NMPSTID") AND ("VMPT"."WDTRANNUM" = "VMPTSV"."WDTRANNUM"))
AND (("VMPT"."NMPSTID"="VMPTEQ"."NMPSTID") AND ("VMPT"."WDTRANNUM"="VMPTEQ"."WDTRANNUM"))
AND (("VMPT"."NMDOCID"="VMDTEQ"."NMDOCID") AND ("VMPT"."WDDTTRNUM"="VMDTEQ"."WDTRANNUM"))
AND (("VMPTEQ"."TXEQUP"="VMMTRM"."TXEQUP") AND ("VMPTEQ"."TXMETER"="VMMTRM"."TXMETER"))
AND "VMPTEQ"."TXEQUP" = "VMEQUP"."TXEQUP"
AND (("VMPTSV"."WDSERVTYPE"="VMSERV"."WDTYPE") AND ("VMPTSV"."TXSERV"="VMSERV"."TXSERV")) 
在 mysql 中，如果标识符（即表名、列名）是保留字，则必须用反引号括起来，而您的标识符都不是，因此可能会丢失双引号。另外 oj （无论是什么）分配的别名并不是特别有用，所以我会丢失这些别名和括号。例如
还有问题吗？添加所有表定义。
