My package name is 'PackageTest1' , since at the time of creation i had given that name.
But while writing this query
select text from user_source where name='PacklageTest1'no row is selected, and when i give this command
select text from user_source where name='PACKAGETEST1'defination is shown .But why only capital letter package name is identified ?One reason is that the names are different; there's an 'l' (5th character) in 'PacklageTest1', but not in 'PACKAGETEST1'.
A more subtle reason is that identifiers in Oracle are case-sensitive. You can have one package called
"PackageTest1", another called
"Packagetest1" (with a small 't'), another called
"PACKAGETEST1" (all capitals), another called
"pAckAgEtEst1" (vowels capitalized),
all in the same schema.
Normally, the parser capitalizes all unquoted text, so if you say
EXEC  packagetest1.foo ('Hello, world!');what actually gets compiled is
EXEC  PACKAGETEST1.FOO ('Hello, world!');If you actually have an identifier with lower-case letters, then you have to use quotes around it; double-quotes, in places where you don't want it mistaken for a string literal:
EXEC  "PackageTest1"."Foo" ('Hello, world!');or single-quotes when it really is a string literal:
select       text                     -- Column name is actually TEXT, but lower-case will work here
from      user_source                -- View name is actually USER_SOURCE, but lower-case will work here
where     name     = 'PackageTest1'     -- String literal is already quoted
and       type     = 'PACKAGE BODY'     -- If you don't want source code from package spec mixed in
order by  line                    -- Only way to make sure output is in order
