How to solve ORA-04044: procedure, function, package, or type is not allowed here

How to solve ORA-04044: procedure, function, package, or type is not allowed here

While creating shell script some time we face error

ORA-04044: procedure, function, package, or type is not allowed here

NOTE:

this is because we are using tables containing '$' SYMBOL and when ever we use tables like v$session,v$log,v$logfile etc shell script take '$' SYMBOL as shell variables and then while reading script it gives error

ORA-04044: procedure, function, package, or type is not allowed here

SOLUTION:-

for overcome this error always use escape '\' SYMBOL before '$' SYMBOL in table name

like we are use

select * from v$session;

select * from v$log;

in shell script we have to use

select * from v\$session;

select * from v\$log;

and this will solve our error and sucessfully run our shell script.
