+## Query
+
+```
+select * from mysql_table where k1 > 1000 and k3 ='term';
+```
+
+In some cases, the keywords in the database might be used as the field names. For queries to function normally in these cases, Doris will add escape characters to the field names and tables names in SQL statements based on the rules of different databases, such as (``) for MySQL, ([]) for SQLServer, and ("") for PostgreSQL and Oracle. This might require extra attention on case sensitivity. You can view the query statements sent to these various databases via ```explain sql```.
+
+## Write Data
+
+<version since="1.2.2">
+After creating a JDBC Catalog in Doris, you can write data or query results to it using the `insert into` statement. You can also ingest data from one JDBC Catalog Table to another JDBC Catalog Table.
+</version>
+
+Example:
+
+```
+insert into mysql_table values(1, "doris");
+insert into mysql_table select * from table;
+```
+
+### Transaction
+
+In Doris, data is written to External Tables in batches. If the ingestion process is interrupted, rollbacks might be required. That's why JDBC Catalog Tables support data writing transactions. You can utilize this feature by setting the session variable: `enable_odbc_transcation `.
+
+```
+set enable_odbc_transcation = true; 
+```
+
+The transaction mechanism ensures the atomicity of data writing to JDBC External Tables, but it reduces performance to a certain extent. You may decide whether to enable transactions based on your own tradeoff.

+## 数据查询
+
+```sql
+select * from mysql_table where k1 > 1000 and k3 ='term';
+```
+由于可能存在使用数据库内部的关键字作为字段名，为解决这种状况下仍能正确查询，所以在SQL语句中，会根据各个数据库的标准自动在字段名与表名上加上转义符。例如 MYSQL(``)、PostgreSQL("")、SQLServer([])、ORACLE("")，所以此时可能会造成字段名的大小写敏感，具体可以通过explain sql，查看转义后下发到各个数据库的查询语句。
+
+## 数据写入
+
+<version since="1.2.2">
+在Doris中建立JDBC Catalog后，可以通过insert into语句直接写入数据，也可以将Doris执行完查询之后的结果写入JDBC Catalog，或者是从一个JDBC外表将数据导入另一个JDBC外表。
+</version>
+
+示例：
+
+```sql
+insert into mysql_table values(1, "doris");
+insert into mysql_table select * from table;
+```
+### 事务
+
+Doris的数据是由一组batch的方式写入外部表的，如果中途导入中断，之前写入数据可能需要回滚。所以JDBC外表支持数据写入时的事务，事务的支持需要通过设置session variable: `enable_odbc_transcation `。
+
+```sql
+set enable_odbc_transcation = true; 
+```
+
+事务保证了JDBC外表数据写入的原子性，但是一定程度上会降低数据写入的性能，可以考虑酌情开启该功能。
