Mybatis中可以使用JSTL標簽

動態刪除表

Mapper

void deleteTable(@Param("tableName") String tableName);

Mapper.xml

<update id="deleteTable">DROP TABLE ${tableName} </update>

動態創建表

Mapper

void createTable(@Param("newTableName") String newTableName, @Param("columns") List<Map<String, String>> columns);

Mapper.xml

<update id="createTable">CREATE TABLE ${newTableName} ("ID" VARCHAR2(64 BYTE) PRIMARY KEY NOT NULL,<foreach item="item" index="index" collection="columns" open="" separator="," close=",">"${item.code}"<choose><when test="item.type=='STRING'">VARCHAR2(${item.length} BYTE) NULL</when><when test="item.type=='NUMBER'">NUMBER(${item.length}，${column.precision}) NULL</when><otherwise>TIMESTAMP(${item.length}) NULL</otherwise></choose></foreach>"CREATE_TIME" TIMESTAMP(6) NULL ,"MODIFY_TIME" TIMESTAMP(6) NULL) </update>

或者

Mapper

void createTableColumn(@Param("newTableName") String newTableName, @Param("column") Map<String, String> column);

Mapper.xml

<update id="createTableColumn" parameterType="java.util.Map">CREATE TABLE ${newTableName} ("ID" VARCHAR2(64 BYTE) PRIMARY KEY NOT NULL,"CREATE_TIME" TIMESTAMP(6) NULL ,"MODIFY_TIME" TIMESTAMP(6) NULL ,"${column.code}"<choose><when test="column.type=='STRING'">VARCHAR2(${column.length} BYTE) NULL</when><when test="column.type=='NUMBER'">NUMBER(${column.length},${column.precision}) NULL</when><otherwise>TIMESTAMP(${column.length}) NULL</otherwise></choose>) </update>
