修饰符和类型	方法	说明
`static String`	`escapeSingleQuota(String origin)`
`static String`	`formatTimestamp(Timestamp timestamp)`
`static ClassLoader`	`getClassLoader()`
`static String`	`getNativeSql(String rawSql, Object[] parameters)`
`static int`	`guessTimestampPrecision(String value)`
`static <T> T`	`newInstance(Class<T> c)`	Instantiate the class
`static Class<?>`	`parseClassType(String key)`
`static Date`	`parseDate(String timestampStr)`
`static Time`	`parseTime(String timestampStr)`
`static Timestamp`	`parseTimestamp(String timeStampStr)`
`static String`	`preprocessSql(String rawSql)`	Some of the SQLs sent by other popular frameworks or tools like Spark, contains syntax that cannot be parsed by the TDengine client.

public static Time parseTime(String timestampStr)
                      throws DateTimeParseException

public static Date parseDate(String timestampStr)

public static Timestamp parseTimestamp(String timeStampStr)

public static String escapeSingleQuota(String origin)

public static String getNativeSql(String rawSql,
                                  Object[] parameters)

public static String formatTimestamp(Timestamp timestamp)

public static int guessTimestampPrecision(String value)

preprocessSql
```
public static String preprocessSql(String rawSql)
```
Some of the SQLs sent by other popular frameworks or tools like Spark, contains syntax that cannot be parsed by the TDengine client. Thus, some simple parsers/filters are intentionally added in this JDBC implementation in order to process those supported SQLs.

public static ClassLoader getClassLoader()

public static Class<?> parseClassType(String key)

public static <T> T newInstance(Class<T> c)

Instantiate the class
