在下面的shell脚本中定义字符串数组。我想显示sql nomal，我该怎么办？

a=("select * from t1;"
"select * from t2;"
"select  from t3;")

这会为你做到

a=( 'select * from t1;'
    'select * from t2;'
    'select * from t3;' )


for query in "${a[@]}"; do
  echo "$query"
done

$ sh SO.sh 
select * from t1;
select * from t2;
select * from t3;
