exact() Function

Function

exact( text1, text2 )

Compares two given text strings in a case-sensitive manner, returning true only if they are exactly the same.

Parameters

Keyword Type Description

text1

Text

One of two strings that will be compared.

text2

Text

The other string that will be compared.

Returns

Boolean

Usage considerations

When comparing text strings, using this function over the = operator improves performance. The = operator, however, is case-insensitive. Only use the exact() function when case-insensitivity is not a requirement.

Examples

Text

Comparing exact copies

1
exact("HELLO", "HELLO")

Returns true.

Comparing text that differs only by case

1
exact("Hello", "HELLO")

Returns false.

Comparing different text

1
exact("Hello", "World")

Returns false.

Other Types

Comparing non-text values

1
exact(123, 123)

Returns true. Values of other scalar types are compared in the same way as =.

Comparing text from a dictionary without casting

exact(
  "Hello",
  { dictionaryKey: "Hello" }.dictionaryKey
)

Comparing text from a map or CDT

exact(

)

Comparing lists and single values

1
exact({ "Hello" }, "Hello")

Returns false. Lists are not considered equal to scalar values.
