+<p>Selects data from a table. <code>DISTINCT</code> filters out duplicate results while <code>ALL</code>, the default, includes all results. <code>FROM</code> identifies the table being queried (single table only currently - no joins or derived tables yet). Dynamic columns not declared at create time may be defined in parenthesis after the table name and then used in the query. <code>GROUP BY</code> groups the the result by the given expression(s). <code>HAVING</code> filter rows after grouping. <code>ORDER BY</code> sorts the result by the given column(s) or expression(s) and is only allowed for aggregate queries or queries with a <code>LIMIT</code> clause. <code>LIMIT</code> limits the number of rows returned by the query with no limit applied if specified as null or less than zero. The <code>LIMIT</code> clause is executed after the <code>ORDER BY</code> clause to support TopN type queries. An optional hint overrides the default query plan.</p>

+<p>Inserts if not present and updates otherwise rows in the table based on the results of running another query. The values are set based on their matching position between the source and target tables. The list of columns is optional and if not present will map to the column in the order they are declared in the schema. If auto commit is on, and both a) the target table matches the source table, and b) the select performs no aggregation, then the population of the target table will be done completely on the server-side (with constraint violations logged, but otherwise ignored). Otherwise, data is buffered on the client and, if auto commit is on, committed in row batches as specified by the UpsertBatchSize connection property (or the phoenix.mutate.upsertBatchSize <code>HBase</code> config property which defaults to 10000 rows)</p>

+<p>Creates a new table or view. For the creation of a table, the <code>HBase</code> table and any column families referenced are created if they don't already exist (using uppercase names unless they are double quoted in which case they are case sensitive). Column families outside of the ones listed are not affected. At create time, an empty key value is added to the first column family of any existing rows. Upserts will also add this empty key value. This is done to improve query performance by having a key value column we can guarantee always being there (minimizing the amount of data that must be projected). Alternately, if a view is created, the <code>HBase</code> table and column families must already exist. No empty key value is added to existing rows and no data mutations are allowed - the view is read-only. Query performance for a view will not be as good as performance for a table. For a table only, <code>HBase</code> table and column configuration options may be passed
through as key/value pairs to setup the <code>HBase</code> table as needed.</p>

+<p>Creates a new secondary index on a table or view. The index will be automatically kept in sync with the table as the data changes. At query time, the optimizer will use the index if it contains all columns referenced in the query and produces the most efficient execution plan. If a table has rows that are write-once and append-only, then the table may set the <code>IMMUTABLE_ROWS</code> property to true (either up-front in the <code>CREATE TABLE</code> statement or afterwards in an <code>ALTER TABLE</code> statement). This reduces the overhead at write time to maintain the index. Otherwise, if this property is not set on the table, then incremental index maintenance will be performed on the server side when the data changes.</p>

+<p>Sets an option on an <code>HBase</code> table or column by modifying the respective <code>HBase</code> metadata. The option applies to the named family or if omitted to all families if the name references an <code>HColumnDescriptor</code> property. Otherwise, the option applies to the <code>HTableDescriptor</code>.</p><p>One built-in option is <code>SALT_BUCKETS</code>. This option causes an extra byte to be transparently prepended to every row key to ensure an even distribution of write load across all your region servers. This is useful when your row key is always monotonically increasing causing hot spotting on a single region server. The byte is determined by hashing the row key and modding it with the <code>SALT_BUCKETS</code> value. The value may be from 1 to 256. If not split points are defined for the table, it will automatically be pre-split at each possible salt bucket value. For an excellent write-up of this technique, see http://blog.sematext.com/2012/04/09/hbasewd-av
oid-regionserver-hotspotting-despite-writing-records-with-sequential-keys/</p><p>Another built-in options is <code>IMMUTABLE_ROWS</code>. Only tables with immutable rows are allowed to have indexes. Immutable rows are expected to be inserted once in their entirety and then never updated. This limitation will be removed once incremental index maintenance has been implemented. The current implementation inserts the index rows when the data row is inserted.</p>

+<p>Advanced features that overrides default query processing behavior. The supported hints include 1) <code>SKIP_SCAN</code> to force a skip scan to be performed on the query when it otherwise would not be. This option may improve performance if a query does not include the leading primary key column, but does include other, very selective primary key columns. 2) <code>RANGE_SCAN</code> to force a range scan to be performed on the query. This option may improve performance if a query filters on a range for non selective leading primary key column along with other primary key columns 3) <code>NO_INTRA_REGION_PARALLELIZATION</code> to prevent the spawning of multiple threads to process data within a single region. This option is useful when the overall data set being queries is known to be small. 4) <code>NO_INDEX</code> to force the data table to be used for a query, and 5) <code>INDEX</code>(<table_name> <index_name>...) to suggest which index to use for a given query. D
ouble quotes may be used to surround a table_name and/or index_name that is case sensitive.</p>
+<p>Example:</p>
+<p class="notranslate">/*+ SKIP_SCAN */<br />/*+ RANGE_SCAN */<br />/*+ NO_INTRA_REGION_PARALLELIZATION */<br />/*+ NO_INDEX */<br />/*+ INDEX(employee emp_name_idx emp_start_date_idx) */</p>

+<p>A row value constructor is a list of other terms which are treated together as a kind of composite structure. They may be compared to each other or to other other terms. The main use case is 1) to enable efficiently stepping through a set of rows in support of query-more type functionality, or 2) to allow <code>IN</code> clause to perform point gets on composite row keys.</p>
