Table schema

Problem description

Expected Behaviour: When executing the following query, return the correct data SELECT Bar from Foo WHERE (Bar = 'test')
Actual behaviour: Error thrown: “Incorrect syntax near the keyword ‘FROM’.”
Error message/stack trace: Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'FROM'. at com.microsoft.sqlserver.jdbc.SQLServerException.makeFromDatabaseError(SQLServerException.java:254) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.getNextResult(SQLServerStatement.java:1608) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.doExecuteStatement(SQLServerStatement.java:859) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement$StmtExecCmd.doExecute(SQLServerStatement.java:759) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.TDSCommand.execute(IOBuffer.java:7240) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerConnection.executeCommand(SQLServerConnection.java:2869) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeCommand(SQLServerStatement.java:243) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeStatement(SQLServerStatement.java:218) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerStatement.executeQuery(SQLServerStatement.java:688) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerParameterMetaData.<init>(SQLServerParameterMetaData.java:653) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.getParameterMetaData(SQLServerPreparedStatement.java:3057) ~[mssql-jdbc-7.0.0.jre8.jar:na] at com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement.getParameterMetaData(SQLServerPreparedStatement.java:3068) ~[mssql-jdbc-7.0.0.jre8.jar:na] at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.getParameterMetaData(DelegatingPreparedStatement.java:221) ~[tomcat-dbcp.jar:7.0.92] at org.apache.tomcat.dbcp.dbcp.DelegatingPreparedStatement.getParameterMetaData(DelegatingPreparedStatement.java:221) ~[tomcat-dbcp.jar:7.0.92]
Any other details that can be helpful: It looks like the parser for getting the metadata is including preceding parenthesis when it parses for column names. If turn off metadata checking, it works just fine with the preceding parenthesis When I re-enable metadata checking, the following SQL statement works just fine, returning rows. Note the space between ( and Bar SELECT Bar from Foo WHERE ( Bar = 'test')

@peterbae - Thanks. Looks to me like the opening parenthesis just may need to be included in the delimiter string in the StringTokenizer here. Hope that helps. For now, I’ll just not get the metadata.
