H2 org.h2.jdbc.JdbcSQLSyntaxErrorException occurs when executing a script file in a h2 database

I have used java -cp h2-1.4.199.jar org.h2.tools.RunScript -url jdbc:h2:mem:db1 -script infra_params.sql command to execute below sql script in a H2 database.

infra_params.sql file:-

DROP TABLE IF EXISTS `infrastructure_parameter`; CREATE TABLE `infrastructure_parameter` ( `id` varchar(36) NOT NULL, `created_timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `modified_timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, `NAME` varchar(255) DEFAULT NULL, `PROPERTIES` varchar(255) DEFAULT NULL, `ready` tinyint(1) DEFAULT '0', `TYPE` varchar(255) DEFAULT NULL, PRIMARY KEY (`id`), UNIQUE KEY `UNQ_infrastructure_parameter_0` (`NAME`,`PROPERTIES`) ) ENGINE=InnoDB DEFAULT CHARSET=UTF8; LOCK TABLES `infrastructure_parameter` WRITE; 

But it gives following exception:-

Exception in thread "main" org.h2.jdbc.JdbcSQLSyntaxErrorException: Syntax error in SQL statement " LOCK[*] TABLES `INFRASTRUCTURE_PARAMETER` WRITE "; SQL statement: LOCK TABLES `infrastructure_parameter` WRITE [42000-199] at org.h2.message.DbException.getJdbcSQLException(DbException.java:451) at org.h2.message.DbException.getJdbcSQLException(DbException.java:427) at org.h2.message.DbException.get(DbException.java:205) at org.h2.message.DbException.get(DbException.java:181) at org.h2.message.DbException.getSyntaxError(DbException.java:229) at org.h2.command.Parser.getSyntaxError(Parser.java:989) at org.h2.command.Parser.parsePrepared(Parser.java:951) at org.h2.command.Parser.parse(Parser.java:788) at org.h2.command.Parser.parse(Parser.java:764) at org.h2.command.Parser.prepareCommand(Parser.java:683) at org.h2.engine.Session.prepareLocal(Session.java:627) at org.h2.engine.Session.prepareCommand(Session.java:565) at org.h2.jdbc.JdbcConnection.prepareCommand(JdbcConnection.java:1292) at org.h2.jdbc.JdbcStatement.executeInternal(JdbcStatement.java:217) at org.h2.jdbc.JdbcStatement.execute(JdbcStatement.java:205) at org.h2.tools.RunScript.process(RunScript.java:261) at org.h2.tools.RunScript.process(RunScript.java:192) at org.h2.tools.RunScript.process(RunScript.java:328) at org.h2.tools.RunScript.runTool(RunScript.java:143) at org.h2.tools.RunScript.main(RunScript.java:70) 

Any help on how to fix this issue would be appreciated.
