Example 1 with AddDefaultValueStatement

use of liquibase.statement.core.AddDefaultValueStatement in project liquibase by liquibase.

the class AddAutoIncrementChange method generateStatements.

@Override
public SqlStatement[] generateStatements(Database database) {
    if (database instanceof PostgresDatabase) {
        String sequenceName = (getTableName() + "_" + getColumnName() + "_seq");
        String escapedTableName = database.escapeObjectName(getTableName(), Table.class);
        String escapedColumnName = database.escapeObjectName(getColumnName(), Table.class);
        if (escapedTableName != null && escapedColumnName != null && !escapedTableName.startsWith("\"") && !escapedColumnName.startsWith("\"")) {
            sequenceName = sequenceName.toLowerCase();
        }
        String schemaPrefix;
        if (this.schemaName == null) {
            schemaPrefix = database.getDefaultSchemaName();
        } else {
            schemaPrefix = this.schemaName;
        }
        if (schemaPrefix == null) {
            schemaPrefix = "";
        } else {
            schemaPrefix = schemaPrefix + ".";
        }
        return new SqlStatement[] { new CreateSequenceStatement(catalogName, this.schemaName, sequenceName), new SetNullableStatement(catalogName, this.schemaName, getTableName(), getColumnName(), null, false), new AddDefaultValueStatement(catalogName, this.schemaName, getTableName(), getColumnName(), getColumnDataType(), new SequenceNextValueFunction(schemaPrefix + sequenceName)) };
    }
    return new SqlStatement[] { new AddAutoIncrementStatement(getCatalogName(), getSchemaName(), getTableName(), getColumnName(), getColumnDataType(), getStartWith(), getIncrementBy()) };
}

Example 2 with AddDefaultValueStatement

use of liquibase.statement.core.AddDefaultValueStatement in project opennms by OpenNMS.

the class AddNamedAutoIncrementChange method generateStatements.

@Override
public SqlStatement[] generateStatements(final Database database) {
    final List<SqlStatement> statements = new ArrayList<SqlStatement>();
    if (database instanceof PostgresDatabase) {
        String sequenceName = m_sequenceName;
        if (m_sequenceName == null) {
            sequenceName = (getTableName() + "_" + getColumnName() + "_seq").toLowerCase();
            statements.add(new CreateSequenceStatement(getSchemaName(), sequenceName));
        }
        statements.add(new SetNullableStatement(getSchemaName(), getTableName(), getColumnName(), null, false));
        statements.add(new AddDefaultValueStatement(getSchemaName(), getTableName(), getColumnName(), getColumnDataType(), new DatabaseFunction("NEXTVAL('" + sequenceName + "')")));
        return statements.toArray(new SqlStatement[0]);
    } else {
        return super.generateStatements(database);
    }
}
