Jenkins系列之-—08 实现SQL脚本批量执行

 公司内部推广DevOps，全部项目配置CI/CD流水线（Jenkins+SVN+ANT），在代码实现持续集成后，SQL语句自动执行的实现提上日程

一、环境

• Linux环境
• 安装ANT工具，包括ant扩展包---ant-contrib-1.0b3.jar，maven链接
• 下载oracle连接ojdbc5.jar包。

二、思路

步骤1：  从SVN的QL脚本提交路径上，下载所有SQL脚本

步骤2：【shell脚本】：获取日期文件夹名为今天的文件夹下的sql脚本，拷贝到待执行文件夹中。将其中已执行成功的脚本（即存在于bak文件夹中）删掉；

步骤3：【ant脚本】：对待执行脚本排序后，循环执行每条sql语句，执行成功的sql脚本备份到bak文件夹，方便后续执行时排除重复。

三、具体实现

3.1 源码管理

3.2 执行shell

if [ $# -ne 1 ]
then
        echo "Usage: $0 foldername"
        echo "  $0 Exec SQL"
        exit
fi

Workspace=$1
year=`date +%Y`
today=`date +%Y%m%d`
sqlfolder=${Workspace}/svn/${year}/${today}
bakfolder=${Workspace}/sqlbak/${year}/${today}
logfolder=${Workspace}/sqllog

#如果待执行sql文件夹已存在就清空该文件夹，否则创建
if [ -d "runSqlInFolder" ];then
  echo "-----Clean the executed sql folder：/runSqlInFolder-----"
  rm -rf runSqlInFolder/*
else
  mkdir -p ${Workspace}/runSqlInFolder
fi

if [ ! -d "${logfolder}" ];then
  mkdir ${logfolder}
else
  echo "-----Dir ${logfolder} is exist"
fi

#将今天提交到SVN的sql脚本中还未执行过的拷贝到runSqlInFolder文件夹
if [ -d "${sqlfolder}" ];then
  echo '-----Copy the sql file into folder'
  cp -r ${sqlfolder}/* runSqlInFolder
  find runSqlInFolder/ -name '*.jar' |xargs rm -rf
  find runSqlInFolder/ -type d | grep .svn$ | xargs rm -rf
  if [ -d "${bakfolder}" ];then
    cd ${bakfolder}
    find * -type f -name *.sql|xargs -i rm -f ../../../runSqlInFolder/{}
  else
    echo "-----create back folder： ${bakfolder}"
    mkdir -p ${bakfolder}
  fi
else
  echo dir ${sqlfolder} not exist
fi

3.3 Invoke ANT

3.3.1 定义一个target：runSqlInFolder

使用try catch包裹for 循环，for循环中调用execSQL标签（自定义公共方法块，即宏），顺序逐条执行SQL脚本。

    <taskdef resource="net/sf/antcontrib/antlib.xml" classpath="${lib}/ant-contrib-1.0b3.jar"/>
    <target name="runSqlInFolder">
        <echo>Run the SQL at Folder: ${sqlfolder}</echo>
        <echo>DB Host: ${v7uatdb.host}</echo>
        <echo>DB Name: ${v7uatdb.name}</echo>
        <echo>DB User: ${v7uatdb.user}</echo>
        <trycatch property="errMsg">
            <try>
                <for param="folder">
                    <path>
                        <sort xmlns:rcmp="antlib:org.apache.tools.ant.types.resources.comparators">
                            <dirset dir="${sqlfolder}" includes="*" />
                        </sort>
                    </path>
                    <sequential>
                    <echo>SQL Folder: @{folder}</echo>
                    <for param="file">
                        <path>
                            <sort xmlns:rcmp="antlib:org.apache.tools.ant.types.resources.comparators">
                                <fileset dir="@{folder}" includes="*/*.sql" casesensitive="false"/>
                            </sort>
                        </path>
                        <sequential>
                        <echo>SQL: @{file}</echo>
                        <execsql
                            dbhost="${v7uatdb.host}"
                            dbport="${v7uatdb.port}"
                            dbname="${v7uatdb.name}"
                            dbuser="${v7uatdb.user}"
                            dbpwd="${v7uatdb.pwd}"
                            sqlfile="@{file}"
                            logfile="${Sqllogfile}"/>
                        </sequential>
                        <!--<move file="@{file}" todir="${sqlbakdir}/@{folder}"/>
                        folder 包含路径和文件名，所以直接复制file还有点问题，需要截取文件名--目前待研究 -->
                    </for>
                    <move file="@{folder}" todir="${sqlbakdir}"/>
                    </sequential>
                </for>
                <echo>Finished running all SQL</echo>
                <echo>File moved to backup folder:</echo>
                <echo>${sqlbakdir}</echo>
            </try>
            <catch>
                <echo>Error found when running SQL</echo>
                <echo>Log file can be found in:</echo>
                <echo>${sqlbakdir}/err</echo>
                <move file="${Sqllogfile}" todir="${sqlbakdir}/err"/>
                <fail>Error Occur</fail>
            </catch>
            <finally>
            </finally>
        </trycatch>
    </target>

3.3.2 定义execsql标签

通过sql标签执行sql文件，通过record标签记录对应的执行日志并输出。

注意：如果执行procedure就需要设置delimiter，本例中通过SQL文件的命名来区分是不同的SQL类型（procedure，declare等）。

    <macrodef name="execsql" description="Run single SQL file.">
        <attribute name="dbhost" description="Host Name/ IP of the DB"/>
        <attribute name="dbport" description="DB Port"/>
        <attribute name="dbname" description="DB name"/>
        <attribute name="dbuser" description="DB User name"/>
        <attribute name="dbpwd" description="DB Password"/>
        <attribute name="sqlfile" description="SQL file to be run"/>
        <attribute name="logfile" default="sql.log" description="Log file"/>
        <sequential>
            <echo>Log file @{logfile}</echo>
            <record name="@{logfile}" action="start"/>
            <if>
                <contains string="@{sqlfile}" substring="PROCEDURE"/>
                <then>
                    <sql driver="${oracleDriver}"
                        url="jdbc:oracle:thin:@@@{dbhost}:@{dbport}:@{dbname}"
                        userid="@{dbuser}"
                        password="@{dbpwd}"
                        classpathref="classpath"
                        encoding="${encoding}"
                        print="true"
                        autocommit="true"
            delimiter="/"
            delimitertype="row">
                        <transaction src="@{sqlfile}"/>
                    </sql>
                </then>
                <else>
                    <sql driver="${oracleDriver}"
                        url="jdbc:oracle:thin:@@@{dbhost}:@{dbport}:@{dbname}"
                        userid="@{dbuser}"
                        password="@{dbpwd}"
                        encoding="${encoding}"
                        classpathref="classpath"
                        autocommit="true"
                        print="true">
                        <transaction src="@{sqlfile}"/>
                    </sql>
                </else>
            </if>
            <record name="@{logfile}" action="stop"/>
        </sequential>
    </macrodef>
 

更新后

    <macrodef name="execsql" description="Run single SQL file.">
        <attribute name="dbhost" description="Host Name/ IP of the DB"/>
        <attribute name="dbport" description="DB Port"/>
        <attribute name="dbname" description="DB name"/>
        <attribute name="dbuser" description="DB User name"/>
        <attribute name="dbpwd" description="DB Password"/>
        <attribute name="sqlfile" description="SQL file to be run"/>
        <attribute name="logfile" default="sql.log" description="Log file"/>
        <sequential>
            <echo>Log file @{logfile}</echo>
            <record name="@{logfile}" action="start"/>
            <if>
                <contains string="@{sqlfile}" casesensitive="no" substring="PROCEDURE"/>
                <then>
                    <sql driver="${oracleDriver}"

3.4  SVN中存放SQL的文件夹设置

3.5 成功执行效果

四、遇到的问题处理

4.1【问题】如果执行的SQL语句中存在中文，执行完在数据库中保存的数据是乱码

目前常用的两种数据库编码格式为：GBK、UTF-8，也是两种编码风格(ANSI和UNICODE)中的代表

经确认公司数据库采用GBK编码，所以将encoding改为GBK，乱码问题解决，ant文件头设置

<property name="encoding" value="GBK" /><!--UTF-8-->

4.2【问题】如果执行的SQL语句中，有declare，声明变量的，执行declare过程中会报错

delete zssys.WEB_APP_TEMPLATE where C_INTERFACE_ID = '0000-GDCARVA';;
declare
  response clob;
begin
  response := 'aaa';

insert into zssys.WEB_APP_TEMPLATE (C_PK_ID, C_INTERFACE_ID, C_SYSCODE, C_APP_NAME, C_TEMPLATE_REQUEST, C_TEMPLATE_RESPONSE)
values (SYS_GUID(), '0000-GDCARVA', '*', 'test', null, response);
end;

4.3【问题】目前备份脚本是按照模块整体备份的，没有做到单个sql脚本备份，后期优化

五、 参考资料

使用ANT脚本批量执行SQL，并且结合Jenkins自动化构建
