How do I change case sensitive in Oracle?

By default, Oracle identifiers (table names, column names, etc.) are case-insensitive. You can make them case-sensitive by using quotes around them (eg: SELECT * FROM “My_Table” WHERE “my_field” = 1 ).

Is Oracle Select Case Sensitive?

Oracle Text supports case-sensitivity for word and ABOUT queries.

How do you grep a case insensitive?

By default, grep is case sensitive. This means that the uppercase and lowercase characters are treated as distinct. To ignore case when searching, invoke grep with the -i option (or –ignore-case ). Specifying “Zebra” will match “zebra”, “ZEbrA” or any other combination of upper and lower case letters for that string.

What are case sensitive passwords in Oracle 11g?

Case sensitive passwords (and auditing) are a default feature of newly created Oracle 11g databases.

How do I perform case-insensitive searching in Oracle?

Use regular expressions. From Oracle 10g onwards REGEXP_LIKE () is available. You can specify the _match_parameter_ ‘i’, in order to perform case-insensitive searching. In order to use this as an equality operator you must specify the start and end of the string, which is denoted by the carat and the dollar sign.

Are passwords in a 10g database case insensitive?

Users imported from a 10g database have a PASSWORD_VERSIONS value of “10G” and maintain case insensitive passwords independent of the SEC_CASE_SENSITIVE_LOGON parameter setting. Their passwords become case sensitive as soon as they are changed, assuming the SEC_CASE_SENSITIVE_LOGON parameter is set to TRUE.

Is there a way to use regexp_like in case insensitive search?

This information was taken from Oracle case insensitive searches. The article mentions REGEXP_LIKE but it seems to work with good old = as well. In versions older than 10gR2 it can’t really be done and the usual approach, if you don’t need accent-insensitive search, is to just UPPER () both the column and the search expression.
