I am using the below code
tablelist=`SELECT tablename from List`
echo "table list is $tablelist"
Result is displayed as
table list is Table1
Table2
Table3
Table4
I want to iterate through the result. Please suggest how I can achieve this. If I loop through the current tablelist, it prints the whole list in inside loop.
" ${tablelist} " is not a one-line result. It is multiple lines, one entry per line. So... it is best not to treat it as a simple string. You should treat it as a file.
#!/bin/bash
#tablelist=`SELECT tablename from List`
cat >tables.list <<"EnDoFiNpUt"
Table1
Table2
Table3
Table4
EnDoFiNpUt
i=1
#echo "${tablelist}" |
cat tables.list |
while read table
do
echo -e "\t [${i}] TABLE: '${table}' ..."
echo -e "\t\t ... replace this line by some action using '${table}' ...\n"
i=$((i+=1))
done
The output of that looks like this:
[1] TABLE: 'Table1'... ... replace this line by some action using 'Table1'...
[2] TABLE: 'Table2'... ... replace this line by some action using 'Table2'...
[3] TABLE: 'Table3'... ... replace this line by some action using 'Table3'...
[4] TABLE: 'Table4'... ... replace this line by some action using 'Table4'...
