在生产环境中需要部署大量的数据变更。对于新增的表，需要注意权限和同义词等。但是手动去检查这些变更是否生效就很麻烦。而且也不易维护，比如写好了一个脚本，可能在过一段时间，有一些紧急变更，需要把这些变更加进来，可能就忘了更新检查脚本。
考虑到检查的性能,不想查询数据，只需要保证能够正常访问表即可。所以写了如下的sql。目标就是通过shell来生成这样的sql脚本。
比如对于表TEST,检查是否可以访问，如果可以访问，就显示表TEST is accessible...
SELECT decode (count(*),0,rpad(' TEST' ,30,' ')),'is accessible...' comm FROM TEST WHERE ROWNUM
可以采用如下的shell来生成对应的sql脚本。其中需要考虑单引号在awk中的使用。需要转义为 " '\'' "才可以。然后通过sqlplus来直接调用即可。
grep -i "CREATE TABLE" *.*|grep -v "|sort|uniq|awk"|sort|uniq|awk -F"CREATE TABLE" '{print $2}'|uniq|awk '{print "SELECT decode(count(*) ,0 ,rpad('\'' "$1" '\'',30,'\'' '\'')) tab_name,'\'' is accessible... '\'' comm FROM "$1" WHERE ROWNUMsanity_check.sql
sqlplus -s $1 set pages 0
@sanity_check.sql
!rm sanity_check.sql
EOF
来看看效果。
