How would I run the following query, like I would again mysql:
SELECT * FROM [integrated-myth-15.testing_data_100k]
WHERE title='down in la'
Now it will match if I have a perfect case-sensitive string match, but how would I do it case insensitive for "down in la"? I'm working from the Web console.
I was stunned when some of my BigQuery queries were taking a minute or so, instead of the usual few seconds. The culprit: Case insensitive searches.
Case Sensitivity - Unlike most RDBMS, BigQuery is case sensitive, not only for string comparison, but for object names as well.
If you want to remove a specific character from your String then you can use the Trimming function to do so. Based on the position of the character that you wish to remove there are three kinds of BigQuery String Functions: TRIM (value1[, value2]): It removes all the leading and trailing characters that match value2.
The COALESCE function in BigQuery will return the first non-NULL expression. It's often used to safely handle NULL values.
The standard way to do this is using LOWER
or UPPER
on the input string, e.g.:
#legacySQL
SELECT * FROM [integrated-myth-15.testing_data_100k]
WHERE LOWER(title) = 'down in la';
Or:
#standardSQL
SELECT * FROM `integrated-myth-15.testing_data_100k`
WHERE LOWER(title) = 'down in la';
