8Query

Easy to build selection and selectionArgs for sql.

A SQLiteQueryBuilder.appendWhere(where) of whereClause alternative.

Usage

For example:

A = 1 AND B = 2 OR C = 3

Before:

String selection = "A = ? and B = ? OR C = ?";
String[] selectionArgs = new String[] { "1", "2", "3" };

getContentResolver().query(uri, projections, selection, selectionArgs, sortOrder);

After:

Squery squery = $.equal("A", 1).and().equal("B", 2).or().equal("C", 3);

getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, sortOrder);
// whereClause
// String sql = squery.toString(); // (A = '1') AND (B = '2') OR (C = '3')

Orderby:

squery = squery.desc("D").asc("E").limit(10);

getContentResolver().query(uri, projections, squery.selection, squery.selectionArgs, squery.orderBy);

For another example about block:

(A = 1 and B = 2) OR (C = 3)

• 1. Use of()

$.of(
    $.equal("A", 1).and().equal("B", 2)
).or().equal("C", 3);

• 2. Use begin() + end()

$.begin()
  .equal("A", 1).and().equal("B", 2)
 .end()
 .or().equal("C", 3);

• 3. Structured or operator

$.or(
    $.equal("A", 1).and().equal("B", 2),
    $.equal("C", 3)
);

• 4. Structured and operator

$.and(
    $.equal("A", 1),
    $.equal("B", 2)
)
.or()
.equal("C", 3);

• 5. Structured or + and operators

$.or(
    $.and(
        $.equal("A", 1),
        $.equal("B", 2)
    ),
    $.equal("C", 3)
);

Operators

$.in()

squery = $.in("Id", Arrays.asList("1", "2", "3"));
System.out.println(squery.toString()); // (Id IN (1,2,3))

Installation

via jcenter

repositories {
    jcenter()
}

dependencies {
    compile 'com.infstory:squery:1.0.2'
}

Or via jitpack.io

repositories {
    maven {
        url "https://jitpack.io"
    }
}

dependencies {
    compile 'com.github.yongjhih:squery:-SNAPSHOT'
}

For ActiveAndroid

List<Note> notes = new Select().from(Note.class)
    .where(squery.selection, squery.selectionArgs)
    .execute();

Test

$ ./gradlew test
:squery:test

squery.MainTests > testEqual PASSED

squery.MainTests > testCascadedAndOr STANDARD_OUT
    (A = '1') AND (B = '2') OR (C = '3')
    (A = ?) AND (B = ?) OR (C = ?), [1, 2, 3]

squery.MainTests > testCascadedAndOr PASSED

squery.MainTests > testCombineCascadedStructuredAndOr STANDARD_OUT
    (((A = '1') AND (B = '2')) OR ((C = '3')))
    (((A = ?) AND (B = ?)) OR ((C = ?))), [1, 2, 3]
    (((A = '1')) AND ((B = '2'))) OR (C = '3')
    (((A = ?)) AND ((B = ?))) OR (C = ?), [1, 2, 3]
    (((((A = '1')) AND ((B = '2')))) OR ((C = '3')))
    (((((A = ?)) AND ((B = ?)))) OR ((C = ?))), [1, 2, 3]
