Awesome.Data.Sql.Builder

Travis CI:

A small library for building SQL queries in a better way than regular string concatenation.

Clauses can be added in any order.

Mostly for use directly by ADO.NET or micro-ORMs such as Dapper.

Awesome.Data.Sql.Builder.OData

A small helper project that allows transforming ODataQueryOptions<T> directly into a SelectStatement.

Installation

NuGet Awesome.Data.Sql.Builder

Install-Package Awesome.Data.Sql.Builder

NuGet Awesome.Data.Sql.Builder.OData

Awesome.Data.Sql.Builder Usage

Here is a sample unit test from the project.

var statement = SqlStatements.Select(new[] { "u.ID", "u.Name", "u.EmailAddress" })
    .From("Users u")
    .Where("u.IsCool = TRUE")
    .Where("u.Name LIKE @Query")
    .OrderBy("u.Name", false)
    .Limit(3).Offset(6);

var sql = statement.ToSql();

Assert.That(
    sql,
    SqlCompareConstraint.EqualTo(@"SELECT
    u.ID, u.Name, u.EmailAddress
FROM
    Users u
WHERE
    u.IsCool = TRUE AND
    u.Name LIKE @Query
ORDER BY
    u.Name DESC
LIMIT 3 OFFSET 6"));

Different provider

var statement = new SelectStatement(new[] { "u.ID" })
    .From("Users u")
    .Limit(3)
    .Offset(6);

var sql = new SqlServer2012SqlRenderer().RenderSelect(statement);

Assert.That(
    sql,
    SqlCompareConstraint.EqualTo(@"SELECT
    u.ID
FROM
    Users u
OFFSET 6 ROWS
FETCH NEXT 3 ROWS ONLY"));

Awesome.Data.Sql.Builder.OData Usage

var options = ODataQueryOptionsHelper.Build<TestDTO>(
    "$select=Id,Name,Contact/FirstName,Contact/BirthDate,Contact/Address/City&" + 
    "$expand=Contact,Contact/Address&" +
    "$top=10&" +
    "$skip=20");
var result = new ODataQueryOptionsToSqlStatement().ToSelect(options).First();

Assert.That(
    result.ColumnsList,
    Is.EquivalentTo(new[]
    {
        "Id",
        "Name",
        "Contact/FirstName",
        "Contact/BirthDate",
        "Contact/Address/City"
    }));
Assert.That(result.LimitClause, Is.EqualTo("10"));
Assert.That(result.OffsetClause, Is.EqualTo("20"));

Only supports $select, $top, $skip and $inlinecount=allpages for now!
