Hi, community.
I have one small question about how to create a SqlBasicCall in Parser.jj
correctly.
Take TimestampAddFunctionCall as an example, we create it by:
SqlStdOperatorTable.TIMESTAMP_ADD.createCall(s.end(this), args)
As a result, call like “TIMESTAMPADD(arg0, arg1, arg2)” will be formed.
Here is my question:
How does the SqlParser assemble the operands with COMMA correctly?
Since the result is not “TIMESTAMPADD(arg0 arg1, arg2)”, which loses the former
COMMA; or “TIMESTAMPADD(arg0 arg1, arg2)”、“TIMESTAMPADD(arg0 arg1 arg2)”.
I’ve noticed that SqlParserPos is involved, but I’m not sure if it’s relevant.
Any feedback would be awesome.
Best,
ZheHu
