Question

这段代码可以运作但是把所有内容（＆＃34; timestamp8＆＃34;，＆＃34; Last＆＃34;，＆＃34; TradePrice＆＃34;，＆＃34; TradeFlags＆＃34;）放入filname column如何更改它我只想放置＆＃34; gel＆＃34;进入filname（在这种情况下为$ table = gel）

我尝试凝胶＆＃39;它说Parse错误：语法错误，意外＆＃39;凝胶＆＃39;

中的（T_STRING）

请建议

$sql ='INSERT INTO pong8_maintable ("filname","timestamp8","Last","TradePrice", "TradeFlags"

) 

SELECT
"gel" ,
cast(public.'.$table.'."Timestamp" as timestamp) ,
cast(public.'.$table.'."Last" as numeric)  ,
cast(public.'.$table.'."Trade Flags"as varchar)


FROM Public.'.$table; 


sc_exec_sql($sql);

Answer 1

我试着这样做

FOR /L %%A IN (1,1,2) DO (
 xcopy /s C:\Users\abc\def\folder3 C:\Users\xyz\folder%%A
)

或

SELECT
(\''.$table.'\') ,
cast(public.'.$table.'."Timestamp" as timestamp) ,
cast(public.'.$table.'."Last" as numeric)  ,
cast(public.'.$table.'."Trade Price" as numeric)  ,

将常量插入字段（来自select）Postgres
