Build Query Conditions

Query conditions are the set of rules or filters applied to a query to refine the data that will be retrieved. Conditions play a role in limiting the dataset to only the records that meet the specified criteria. This allows users to extract specific and meaningful data from their entities based on their needs.

In a typical query, conditions are used to filter records by specifying property values, using comparison operators, and combining conditions through logical operators like AND and OR. The conditions define the "WHERE" clause in a traditional SQL query.

Key Elements of a Condition

• Property: The field or attribute of an entity being filtered (e.g., Name, Date of Birth, ID).

• Operator: The comparison type (e.g., equals, contains, greater than).

• Value: The data or range to filter the records (e.g., "John", 100, or a date range).

• Logical Operators: Combine multiple conditions (e.g., AND, OR) to refine results.

Using conditions efficiently ensures that only relevant data is fetched, optimizing system performance and improving data handling.
