Spark SQL syntax - INSERT OVERWRITE, RLIKE,DATE 
                 Key: CALCITE-4438
                 URL: https://issues.apache.org/jira/browse/CALCITE-4438

Calcite SQLParser: Calcite throwing error while parsing Spark SQL syntax - 
INSERT OVERWRITE, RLIKE,DATE,DAY,YEAR,MONTH. I am using 1.26.0 version of 
calcite-core and calcite-server.

Also it throws error if year,day,month,identity,value,date is used as alias in 
sql query

For example -

1) DATE QUERIES

{color:#808080}
{color} {color:#000080}val {color}query1 = {color:#008000}"select 
DATE(gns_date) as dt"{color}

{color:#008000}StatementMetadataFragment(com.intuit.superglue.pipeline.parsers.CalciteStatementParser,UNKNOWN,List(),List(),List(org.apache.calcite.sql.parser.SqlParseException:

{color:#008000}
{color} {color:#000080}val {color}query3 = {color:#008000}"select 
date('2020-11-07') as date"
{color}

{color:#008000} {color:#000080}val {color}query3 = "select loan_id as year, 
as_of_date as date"{color}

{color:#008000}val query4="{color}{color:#008000}select \{D'1990-01-01'} as 
day,a as month from table{color}{color:#008000}"{color}

{color:#008000}2) INSERT OVERWRITE{color}

{color:#008000}INSERT OVERWRITE TABLE sbg_schema.tableA
select distinct SURV_MARK_CUST_IDEN
,latest_surv_oci
,tran_mark_cust_iden
,surv_tran_mci
,orgz_mark_cust_iden from tableB
{color}

{color:#008000}StatementMetadataFragment(com.intuit.superglue.pipeline.parsers.CalciteStatementParser,UNKNOWN,List(),List(),List(org.apache.calcite.sql.parser.SqlParseException:

{color:#008000}3) RLIKE{color}

{color:#000080}val {color}query1 = {color:#008000}"select cola from tableA 
where MAX(realm_email) rlike 
'.+@.+{color}{color:#000080}\\\\{color}{color:#008000}..+'"
{color}

 Encountered "rlike" at line 1, column 48.{color}

 

{color:#008000}All these queries are correctly being parsed via SPARK SQL . But 
calcite's parser grammer file doesn't suport these tokens{color}

 

*{color:#008000}This is the code for creating sqlParser instance:{color}*

{color:#008000}object Spark3SqlDialect{
 val DefaultContext: SqlDialect.Context = SqlDialect.EMPTY_CONTEXT
 .withDatabaseProduct(SqlDialect.DatabaseProduct.SPARK)
 .withNullCollation(NullCollation.LOW)
 .withCaseSensitive(false)
 .withConformance(SqlConformanceEnum.BABEL)
 .withIdentifierQuoteString("`")
 .withQuotedCasing(Casing.UNCHANGED)
 .withUnquotedCasing(Casing.UNCHANGED)
 val DEFAULT = new SparkSqlDialect(DefaultContext)
}{color}

{color:#008000}
val sqlParser: SqlParser = SqlParser.create(sqlQuery, 
createSqlParserConfig()){color}

{color:#008000}
private def createSqlParserConfig() = {
 Spark3SqlDialect.DEFAULT.configureParser(SqlParser.config()
 .withParserFactory(SqlDdlParserImpl.FACTORY))
 .withConformance(SqlConformanceEnum.BABEL)
 }{color}
