PostgresMessage.Error.Field

Topics

Enumeration Cases

• case columnName
  Column name: if the error was associated with a specific table column, the name of the column. (Refer to the schema and table name fields to identify the table.)
• case constraintName
  Constraint name: if the error was associated with a specific constraint, the name of the constraint. Refer to fields listed above for the associated table or domain. (For this purpose, indexes are treated as constraints, even if they weren’t created with constraint syntax.)
• case dataTypeName
  Data type name: if the error was associated with a specific data type, the name of the data type. (Refer to the schema name field for the name of the data type’s schema.)
• case detail
  Detail: an optional secondary error message carrying more detail about the problem. Might run to multiple lines.
• case file
  File: the file name of the source-code location where the error was reported.
• case hint
  Hint: an optional suggestion what to do about the problem. This is intended to differ from Detail in that it offers advice (potentially inappropriate) rather than hard facts. Might run to multiple lines.
• case internalPosition
  Internal position: this is defined the same as the P field, but it is used when the cursor position refers to an internally generated command rather than the one submitted by the client. The q field will always appear when this field appears.
• case internalQuery
  Internal query: the text of a failed internally-generated command. This could be, for example, a SQL query issued by a PL/pgSQL function.
• case line
  Line: the line number of the source-code location where the error was reported.
• case localizedSeverity
  Severity: the field contents are ERROR, FATAL, or PANIC (in an error message), or WARNING, NOTICE, DEBUG, INFO, or LOG (in a notice message), or a localized translation of one of these. Always present.
• case locationContext
  Where: an indication of the context in which the error occurred. Presently this includes a call stack traceback of active procedural language functions and internally-generated queries. The trace is one entry per line, most recent first.
• case message
  Message: the primary human-readable error message. This should be accurate but terse (typically one line). Always present.
• case position
  Position: the field value is a decimal ASCII integer, indicating an error cursor position as an index into the original query string. The first character has index 1, and positions are measured in characters not bytes.
• case routine
  Routine: the name of the source-code routine reporting the error.
• case schemaName
  Schema name: if the error was associated with a specific database object, the name of the schema containing that object, if any.
• case severity
  Severity: the field contents are ERROR, FATAL, or PANIC (in an error message), or WARNING, NOTICE, DEBUG, INFO, or LOG (in a notice message). This is identical to the S field except that the contents are never localized. This is present only in messages generated by PostgreSQL versions 9.6 and later.
• case sqlState
  Code: the SQLSTATE code for the error (see Appendix A). Not localizable. Always present.
• case tableName
  Table name: if the error was associated with a specific table, the name of the table. (Refer to the schema name field for the name of the table’s schema.)

Initializers

• init?(rawValue: UInt8)
  Creates a new instance with the specified raw value.
