Job-Ready SQL in an Afternoon - Conditional Filtering Grouped Comparisons

The video tutorial covers SQL filtering techniques, including equality and inequality checks, pattern matching with LIKE and wildcards, case-insensitive searches using ILIKE, and filtering with IN and BETWEEN for specific values and ranges. It explains how to use these SQL statements effectively to retrieve desired data from a database.

What is a limitation of using equality operators when filtering records with multiple components?

• They cannot be used with text fields.

• They are case-sensitive by default.

• They require exact matches, which may not work for composite records.

• They can only filter numeric values.

Which wildcard character allows for any number of characters before or after a specified string in a LIKE query?

• Underscore (_)

• Percent (%)

• Asterisk (*)

• Question mark (?)

What does the underscore (_) wildcard represent in a SQL pattern search?

• Any number of characters

• A single character

• A numeric character

• A space character

How does the ILIKE keyword differ from LIKE in SQL?

• ILIKE is case-sensitive.

• ILIKE is used for numeric comparisons.

• ILIKE requires exact matches.

• ILIKE is case-insensitive.

Which SQL keyword allows you to filter records based on a list of specific values?

• BETWEEN

• LIKE

• IN

• JOIN

What is the advantage of using the IN keyword over multiple OR conditions?

• It allows for case-insensitive searches.

• It automatically sorts the results.

• It is more readable and concise.

• It can only be used with numeric values.

How does the BETWEEN keyword function in SQL?

• It combines multiple tables into one.

• It selects records within a specified range of values.

• It filters records that match a specific pattern.

• It excludes records with null values.

What does the NOT BETWEEN keyword do in a SQL query?

• It combines multiple tables into one.

• It excludes records with null values.

• It filters records that match a specific pattern.

• It selects records outside a specified range.

Which keyword would you use to exclude records that match a specific pattern?

• FILTER

• IGNORE

• EXCLUDE

• NOT LIKE

What is the purpose of using NOT IN in a SQL query?

• To filter records based on a pattern.

• To exclude records that match any value in a list.

• To combine multiple tables into one.

• To include records with null values.
