ASBITSTREAM - additive expression as value of parameter

[SergeyPugachyov]

The code is:

DECLARE IN_STR_BLOB BLOB ASBITSTREAM(IN_STR_ROW.IN_STR CCSID 1208 SET MESSAGESET TYPE functionName || '_IN' FORMAT 'Str');

The test ParsingErrorCheck failed because of concatination ||. To fix it you can modify method in the file esql-frontend\src\main\java\com\exxeta\iss\sonar\esql\parser\EsqlGrammar.java:

	public AsbitstreamFunctionTreeImpl ASBITSTREAM_FUNCTION() {
		return b.<AsbitstreamFunctionTreeImpl>nonterminal(Kind.ASBITSTREAM_FUNCTION).is(f.asbitstreamFunction(
				b.token(EsqlNonReservedKeyword.ASBITSTREAM), b.token(EsqlPunctuator.LPARENTHESIS),
				FIELD_REFERENCE(),b.optional(b.firstOf( 
					b.oneOrMore(f.newTuple106(b.token(EsqlPunctuator.COMMA), b.optional(CALL_EXPRESSION()))),
					b.oneOrMore(f.newTuple107(b.firstOf(
						b.token(EsqlNonReservedKeyword.OPTIONS), 
						b.token(EsqlNonReservedKeyword.ENCODING), 
						b.token(EsqlNonReservedKeyword.CCSID), 
						b.token(EsqlNonReservedKeyword.SET), 
						b.token(EsqlNonReservedKeyword.TYPE), 
						b.token(EsqlNonReservedKeyword.FORMAT)
					), b.optional(CALL_EXPRESSION())))
					  )),
				b.token(EsqlPunctuator.RPARENTHESIS)
				
		));
	}

To this (very important to set ADDITIVE_EXPRESSION() on the first place):

	public AsbitstreamFunctionTreeImpl ASBITSTREAM_FUNCTION() {
		return b.<AsbitstreamFunctionTreeImpl>nonterminal(Kind.ASBITSTREAM_FUNCTION).is(f.asbitstreamFunction(
				b.token(EsqlNonReservedKeyword.ASBITSTREAM), b.token(EsqlPunctuator.LPARENTHESIS),
				FIELD_REFERENCE(),b.optional(b.firstOf(
					b.oneOrMore(f.newTuple106(b.token(EsqlPunctuator.COMMA), b.optional(CALL_EXPRESSION()))),
					b.oneOrMore(f.newTuple107(b.firstOf(
						b.token(EsqlNonReservedKeyword.OPTIONS),
						b.token(EsqlNonReservedKeyword.ENCODING),
						b.token(EsqlNonReservedKeyword.CCSID),
						b.token(EsqlNonReservedKeyword.SET),
						b.token(EsqlNonReservedKeyword.TYPE),
						b.token(EsqlNonReservedKeyword.FORMAT)
					), b.optional(b.firstOf(ADDITIVE_EXPRESSION(), CALL_EXPRESSION()))))
					  )),
				b.token(EsqlPunctuator.RPARENTHESIS)
				
		));
	}
