Fields

scale :: Maybe Int
For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.
precision :: Maybe Int
For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.
schemaName :: Maybe Text
The schema name (database name) to which the query results belong.
catalogName :: Maybe Text
The catalog to which the query results belong.
caseSensitive :: Maybe Bool
Indicates whether values in the column are case-sensitive.
label :: Maybe Text
A column label.
tableName :: Maybe Text
The table name for the query results.
nullable :: Maybe ColumnNullable
Indicates the column's nullable status.
name :: Text
The name of the column.
type' :: Text
The data type of the column.

Arguments

:: Text	`$sel:name:ColumnInfo'`
-> Text	`$sel:type':ColumnInfo'`
-> ColumnInfo

Create a value of ColumnInfo with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:scale:ColumnInfo', columnInfo_scale - For DECIMAL data types, specifies the total number of digits in the fractional part of the value. Defaults to 0.

$sel:precision:ColumnInfo', columnInfo_precision - For DECIMAL data types, specifies the total number of digits, up to 38. For performance reasons, we recommend up to 18 digits.

$sel:schemaName:ColumnInfo', columnInfo_schemaName - The schema name (database name) to which the query results belong.

$sel:catalogName:ColumnInfo', columnInfo_catalogName - The catalog to which the query results belong.

$sel:caseSensitive:ColumnInfo', columnInfo_caseSensitive - Indicates whether values in the column are case-sensitive.

$sel:label:ColumnInfo', columnInfo_label - A column label.

$sel:tableName:ColumnInfo', columnInfo_tableName - The table name for the query results.

$sel:nullable:ColumnInfo', columnInfo_nullable - Indicates the column's nullable status.

$sel:name:ColumnInfo', columnInfo_name - The name of the column.

$sel:type':ColumnInfo', columnInfo_type - The data type of the column.
