Question

我的项目中有以下代码行使用Apache Derby：

 stmt.executeUpdate("CREATE table "+productName+" (Time FLOAT NOT NULL PRIMARY KEY, AcidNo FLOAT, Viscosity FLOAT, Temperature FLOAT)");

当变量productName以字母开头（即“RedProduct”）时，一切正常。当productName以数字开头（即“6Green”）时，表是创建的，但是我收到以下错误：

java.sql.SQLSyntaxErrorException: Syntax error: Encountered "6" at line 1, column 15.
    at org.apache.derby.impl.jdbc.SQLExceptionFactory40.getSQLException(Unknown Source)
    at org.apache.derby.impl.jdbc.Util.generateCsSQLException(Unknown Source)
    at org.apache.derby.impl.jdbc.TransactionResourceImpl.wrapInSQLException(Unknown Source)
    at org.apache.derby.impl.jdbc.TransactionResourceImpl.handleException(Unknown Source)

    at org.apache.derby.impl.jdbc.EmbedStatement.execute(Unknown Source)
    at org.apache.derby.impl.jdbc.EmbedStatement.executeQuery(Unknown Source)

任何想法？顺便说一下，将表名放在括号中没有用。谢谢！

您是否尝试在奇怪的名称周围加上双引号？

stmt.executeUpdate("CREATE table \"" + productName + 
    "\" (Time FLOAT NOT NULL PRIMARY KEY, AcidNo FLOAT, Viscosity FLOAT, Temperature FLOAT)");

使用Apache Derby创建表时出现SQLSyntaxErrorException
