Release v.2.5.0

• LATERAL queries support (wiki)
• RawStatement support (wiki)
• Expose statement Rows method (wiki)
• Allow Raw helper to accept named arguments (wiki)
• Lossless decimal types conversion (wiki)
• Implicit CROSS JOIN support (wiki)
• SQL builder schema rename support. (wiki)
• [Bug][MySQL] UPDATE statement does not escape reserved word when MODEL is used (issue)
• Allow Bytea literal constructor to accept byte array as well as string
• New literal constructor functions: (wiki)
  • for each of the integer types - Int32(), UInt32(), Int64, UInt64(), etc..
  • for uuid literal - UUID()
  • for exact decimal literal - Decimal()

Release v.2.4.0

Go modules support
For new download procedure take a look at Installation.
Go mod requires for projects with major version 2 or higher, to include major version at the end of the module paths. This means for go.mod projects, depending of go-jet, will have to update there import paths. This can be achieved with the following command:

find . -type f \
    -name '*.go' \
    -exec sed -i -e 's,github.com/go-jet/jet,github.com/go-jet/jet/v2,g' {} \;

For GOPATH projects import path remains the same.

Release v.2.3.0

• Support for WITH statements and Common Table Expressions(CTE). Sample usage.
• [postgres] Support for ON CONFLICT clause (sample)
• [mysql] Support for ON DUPLICATE KEY UDPATE clause (sample)
• New type-safe SET clause for UPDATE statement (sample)
• Generated files idempotency (timestamp removed from generated files) (issue)
• Automatic query logging (sample)

Release v.2.2.0

• Interval type support. Sample usage can be seen here.
• Datetime arithmetic with interval types (ADD/SUB).
• Dynamic projection list support. Sample usage.
• [bug] Escape reserved words used as identifiers in generated SQL(issue).
• [bug] Fix crash on generating enum SQL Builder files when database enum contains numeric values(issue).

Release v.2.1.2

• [bug] Incorrect query result mapping into complex destination when UUID is used as primary key(issue).
• [bug] Query should return error when scanning into struct destination and query result set is empty. Query and QueryContext will now return qrm.ErrNoRows(issue).

Release v.2.1.1

• New aggregate MIN and MAX functions added that accepts any expression type (issue).

Release v.2.1.0

• Window function support. Sample usage can be seen here.
• Database views support
  • Jet generator now generates view sqlbuilder and model types.
  • sqlBuilder types are generated in view folder and will behave the same as table sqlbuilder types.
  • model types are generated in model folder. To use view model type as grouping destination primary_key tag has to be specified manually. More information here.
• Jet internal types are now aliased. This allows passing of manually constructed expression slices as variadic argument of some operators and functions.
• [API break] ColumnList is aliased and reverted to be defined as slice of Columns. This will allow conditionally constructing the list of columns, by appending to a slice, before the statements.
  To fix build, just replace parentheses with braces. ColumnList(.....) -> ColumnList{......}

Release v.2.0.0

Changes:

1. MySQL and MariaDB support:
   • SELECT (DISTINCT, FROM, WHERE, GROUP BY, HAVING, ORDER BY, LIMIT, OFFSET, FOR, UNION, LOCK_IN_SHARE_MODE, sub-queries)
   • INSERT (VALUES, query),
   • UPDATE (SET, WHERE),
   • DELETE (WHERE, ORDER_BY, LIMIT),
   • LOCK (READ, WRITE)
2. PostgreSQL import part has changed: github.com/go-jet/jet -> github.com/go-jet/jet/postgres
3. Query execution mapping will also try to convert result set object to destination type if such a conversion is allowed.
4. For every time type there is now a constructor method that accepts time.Time (DateT, TimeT, TimestampT, TimezT...)
5. Some methods and types are changed or replaced:
   • Sql() and DebuSql does not return error as a last parameter. If there is an error in statement this methods will panic.
   • RAW -> Raw
   • SIMILAR_TO -> REGEXP_LIKE
   • NOT_SIMILAR_TO -> NOT_REGEXP_LIKE
   • ColumnList{column1, ...} -> ColumnList(column1, ...)

Release v.1.0.0

• Auto-generated type-safe SQL Builder
  • Types - boolean, integers(smallint, integer, bigint), floats(real, numeric, decimal, double precision),
    strings(text, character, character varying), date, time(z), timestamp(z) and enums.
  • Statements:
    • SELECT (DISTINCT, FROM, WHERE, GROUP BY, HAVING, ORDER BY, LIMIT, OFFSET, FOR, UNION, INTERSECT, EXCEPT, sub-queries)
    • INSERT (VALUES, query, RETURNING),
    • UPDATE (SET, WHERE, RETURNING),
    • DELETE (WHERE, RETURNING),
    • LOCK (IN, NOWAIT)
• Auto-generated Data Model types - Go types mapped to database type (table or enum), used to store
  result of database queries. Can be combined to create desired query result destination.
• Query execution with result mapping to arbitrary destination structure.
