java – Read data from SQLite where column name contains spaces

Posted by: admin June 15, 2020 Leave a comment


I am having a coulmn name called “condition name” (.sql file has been generated from server)

But in android I am getting following exception while reading data from that table.

12-24 14:34:00.870: W/System.err(269):
android.database.sqlite.SQLiteException: no such column: condition: ,

while compiling:

SELECT condition, category, subcategory,condition name, local path,
remote path, title, content_type FROM library WHERE category = ?

Its not recognizing whole table name and breaking at space.
if you have any ideas please assist me.

How to&Answers:

For quoting identifiers like table/column names, SQLite supports back ticks for compatibility with MySQL, and square brackets for compatibility with SQL Server, but the portable way is to use double quotes:

SELECT "condition name" FROM library

(Single quotes would be used for string values.)


Use single quotes

SELECT 'condition name' FROM library

or double quotes

SELECT "condition name" FROM library

in some cases the name of the table can contain space and even aphostrope, like:

SELECT condition's name FROM library

in this case replace ' with '' in the name of the table:

SELECT 'condition''s' name FROM library
