Using Antlr-grammar for parsing a SQL File, I wanna get the total text value of ~(';')+
in order to log this information I did not parse deeply. Unfortunately, calling getText() on that results only in the last word.
This is the active parsing rule:
...
constraintName=alter_table_constraint_name 'CHECK' content=~(';')+ #alterTableAddCheck
...
which parses this part fine:
ALTER TABLE "UFHDBTBL"."FH01T54"
ADD CONSTRAINT "FH01C54_DYNAMIC" CHECK
(DYNAMIC IN ('Y','N'))
ENFORCED
ENABLE QUERY OPTIMIZATION;
Calling getText() in my program later results in the output of "OPTIMIZATION" only. Anyone an idea, how to get the whole block?
After some testing I found out that content
is of type CommonToken
, ie content
only refers to a single token, hence it doesn't contain all tokens.
A fix could be, to promote the label content
to a contentRule
:
//...
constraintName=alter_table_constraint_name 'CHECK' content=contentRule #alterTableAddCheck
//...
contentRule : ~(';')+;
Or as Sam mentioned here , use this syntax (note the +=
instead of the =
after the label name) and get the complete text by concatenating the individual texts of each list member (this even let's you include whitespace between tokens if wished):
...
constraintName=alter_table_constraint_name 'CHECK' (content+=~';')+ #alterTableAddCheck
...
