HPL/SQL forgot Date and Timestamp types when SELECT INTO variables. for example, current implement will set null, not correct value, to variables for following case, select_into3.sql: declare v_date date; declare v_timestamp timestamp(17, 3); select cast('2019-02-20 12:23:45.678' as date), cast('2019-02-20 12:23:45.678' as timestamp) into v_date, v_timestamp from src limit 1; print 'date: ' || v_date; print 'timestamp: ' || v_timestamp; The result when running : bin/hplsql -f select_into3.sql --trace Configuration file: file:/hive/conf/hplsql-site.xml Parser tree: (program (block (stmt (declare_stmt declare (declare_stmt_item (declare_var_item (ident v_date) (dtype date))))) (stmt (semicolon_stmt ;)) (stmt (declare_stmt declare (declare_stmt_item (declare_var_item (ident v_timestamp) (dtype timestamp) (dtype_len ( 17 , 3 )))))) (stmt (semicolon_stmt ;)) (stmt (select_stmt (fullselect_stmt (fullselect_stmt_item (subselect_stmt select (select_list (select_list_item (expr (expr_spec_func cast ( (expr (expr_atom (string '2019-02-20 12:23:45.678'))) as (dtype date) )))) , (select_list_item (expr (expr_spec_func cast ( (expr (expr_atom (string '2019-02-20 12:23:45.678'))) as (dtype timestamp) ))))) (into_clause into (ident v_date) , (ident v_timestamp)) (from_clause from (from_table_clause (from_table_name_clause (table_name (ident src))))) (select_options (select_options_item limit (expr (expr_atom (int_number 1)))))))))) (stmt (semicolon_stmt ;)) (stmt (print_stmt print (expr (expr_concat (expr_concat_item (expr_atom (string 'date: '))) || (expr_concat_item (expr_atom (ident v_date))))))) (stmt (semicolon_stmt ;)) (stmt (print_stmt print (expr (expr_concat (expr_concat_item (expr_atom (string 'timestamp: '))) || (expr_concat_item (expr_atom (ident v_timestamp))))))) (stmt (semicolon_stmt ;))) <EOF>) Ln:1 DECLARE v_date date Ln:2 DECLARE v_timestamp timestamp Ln:4 SELECT Ln:4 select cast('2019-02-20 12:23:45.678' as date), cast('2019-02-20 12:23:45.678' as timestamp) from src LIMIT 1 Open connection: jdbc:vertica://v001:5433/test (256 ms) Starting query Query executed successfully (55 ms) Ln:4 SELECT completed successfully Ln:4 SELECT INTO statement executed Ln:4 COLUMN: ?column?, Date Ln:4 SET v_date = null Ln:4 COLUMN: ?column?, Timestamp Ln:4 SET v_timestamp = null Ln:12 PRINT date: Ln:13 PRINT timestamp: -- This message was sent by Atlassian JIRA (v7.6.3#76005)
