error when executing a varchar2 in a procedure - sql

I have a varchar2 with an INSERT and I want to execute it in a procedure I try to do it with an execute but this happens:
EXECUTE IMMEDIATE sql_str;
Error:
ERROR at line 1:
ORA-00911: invalid character
ORA-06512: at "SYS.INSERT_MOVIMIENTOS", line 47
ORA-06512: at line 1
Varchar2 carries an insert that is this and works if I paste it but when executing it in the procedure something of the procedure fails.
INSERT INTO MOVIMIENTOS (COD_BANCO, COD_SUCUR, NUM_CTA, FECHA_MOV, TIPO_MOV, IMPORTE) VALUES (2000, 2000, 0, '11/11/08', 'I', 500);
My procedure
CREATE OR REPLACE PROCEDURE INSERT_MOVIMIENTOS (
INSERTMOV_COD_BANCO IN NUMBER,
INSERTMOV_COD_SUCUR IN NUMBER,
INSERTMOV_NUM_CTA IN NUMBER,
INSERTMOV_FECHA_MOV IN DATE,
INSERTMOV_TIPO_MOV IN CHAR,
INSERTMOV_IMPORTE IN NUMBER
)
IS
sql_str VARCHAR2(500) := 'INSERT INTO MOVIMIENTOS (';
movimiento movimientos_typ;
BEGIN
movimiento := movimientos_typ(

IF movimiento.getCOD_BANCO() != 0 THEN

Donot end with the semicolon ; in your query string.
movimiento.getIMPORTE() || ')';
The error is just because of it.
by the way, you should be using bind variables. Dynamically constructing the values this way is vulnerable to SQL Injection.

Problem with PL/SQL anonymous block in an exam

I am working with a code in SQLDeveloper for an exam and I'm having problems with the code. The error shown is
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at line 7
00000 - "PL/SQL: numeric or value error%s"
*Cause: An arithmetic, numeric, string, conversion, or constraint error
occurred. For example, this error occurs if an attempt is made to
assign the value NULL to a variable declared NOT NULL, or if an
attempt is made to assign an integer larger than 99 to a variable
declared NUMBER(2).
*Action: Change the data, how it is manipulated, or how it is declared so
that values do not violate constraints.
The code I'm using is this one:
VAR RUT_CLIENTE VARCHAR2(15);
EXEC :RUT_CLIENTE:= '12487147-9';
DECLARE
V_NOMBRE VARCHAR2(75);
V_RUN VARCHAR2(50);
V_RENTA VARCHAR2(12);
V_EST_CIVIL VARCHAR2(40);
BEGIN
SELECT
CLI.NOMBRE_CLI || ' ' || CLI.APPATERNO_CLI || ' ' || CLI.APMATERNO_CLI,
TO_CHAR(CLI.NUMRUT_CLI || '-' || CLI.DVRUT_CLI),
TO_CHAR(CLI.RENTA_CLI, '$999G999G999'),
EST.DESC_ESTCIVIL
INTO V_NOMBRE, V_RUN, V_RENTA, V_EST_CIVIL
FROM CLIENTE CLI JOIN ESTADO_CIVIL EST
ON CLI.ID_ESTCIVIL = EST.ID_ESTCIVIL
WHERE CLI.NUMRUT_CLI || '-' || CLI.DVRUT_CLI = :RUT_CLIENTE;
DBMS_OUTPUT.PUT_LINE('DATOS DEL CLIENTE');
DBMS_OUTPUT.PUT_LINE(' ');
DBMS_OUTPUT.PUT_LINE('----------------');
DBMS_OUTPUT.PUT_LINE(' ');
DBMS_OUTPUT.PUT_LINE('Nombre: ' || V_NOMBRE);
DBMS_OUTPUT.PUT_LINE('RUN: ' || V_RUN);
DBMS_OUTPUT.PUT_LINE('Estado Civil: ' || V_EST_CIVIL);
DBMS_OUTPUT.PUT_LINE('Renta: ' || V_RENTA);
END;
What am I doing wrong? Also, I have to make this block run three times, each time having to enter a different RUT_CLIENTE (the equivalent of the Social Security number in Chile) to show different results, so should I use a loop for that?
You can avoid such errors if you will use define your variables using the types from your cursor:
DECLARE
cursor cur(p_RUT_CLIENTE) is
SELECT
CLI.NOMBRE_CLI || ' ' || CLI.APPATERNO_CLI || ' ' || CLI.APMATERNO_CLI as col_nombre,
TO_CHAR(CLI.NUMRUT_CLI || '-' || CLI.DVRUT_CLI) as col_run,
TO_CHAR(CLI.RENTA_CLI, '$999G999G999') as col_renta,
EST.DESC_ESTCIVIL as col_est_civil
FROM CLIENTE CLI JOIN ESTADO_CIVIL EST
ON CLI.ID_ESTCIVIL = EST.ID_ESTCIVIL
WHERE CLI.NUMRUT_CLI || '-' || CLI.DVRUT_CLI = p_RUT_CLIENTE;
V_NOMBRE cur.col_nombre%type;
V_RUN cur.col_run%type;
V_RENTA cur.col_renta%type;
V_EST_CIVIL cur.est_civil%type;
BEGIN
open cur(:RUT_CLIENTE)
fetch cur into INTO V_NOMBRE, V_RUN, V_RENTA, V_EST_CIVIL;
close cur;
DBMS_OUTPUT.PUT_LINE('DATOS DEL CLIENTE');
DBMS_OUTPUT.PUT_LINE(' ');
DBMS_OUTPUT.PUT_LINE('----------------');
DBMS_OUTPUT.PUT_LINE(' ');
DBMS_OUTPUT.PUT_LINE('Nombre: ' || V_NOMBRE);
DBMS_OUTPUT.PUT_LINE('RUN: ' || V_RUN);
DBMS_OUTPUT.PUT_LINE('Estado Civil: ' || V_EST_CIVIL);
DBMS_OUTPUT.PUT_LINE('Renta: ' || V_RENTA);
END;

continuing loops a thing in oracle

I am carrying out another exercise to learn various things about Oracle SQL's syntax today's lesson I've chosen are loops. Please see below code where I am trying to have two fields (temp variables) having values being decreased until it's less than zero depending on which of the variables hit's zero depends on what text I would like to output into the script output. Hopefully it makes sense. If I have made any faux pas's please do shout at me.
DECLARE
"Character" VARCHAR2(255);
"Enemy" VARCHAR2(255);
"Character_Health" NUMBER;
"Enemy_Health" NUMBER;
"Character_Attack" NUMBER;
"Enemy_Attack" NUMBER;
BEGIN -- Generates Base Stats
SELECT 'Hero' INTO "Character" FROM dual;
SELECT 'Villain' INTO "Enemy" FROM dual;
SELECT 100 INTO "Character_Health" FROM dual;
SELECT 25 INTO "Enemy_Health" FROM dual;
SELECT 10 INTO "Character_Attack" FROM dual;
SELECT 5 INTO "Enemy_Attack" FROM dual;
dbms_output.put_line ("Character" || ' (' || "Character_Health" || ') VS ' ||' '|| "Enemy" || ' (' || "Enemy_Health" || ')') ;
dbms_output.put_line ('');
dbms_output.put_line ('FIGHT!');
BEGIN -- Round 1
LOOP
dbms_output.put_line ('');
SELECT "Enemy_Health" - "Character_Attack" INTO "Enemy_Health" FROM dual; -- Hero hits Villain
dbms_output.put_line ("Character" || ' Hits ' || "Enemy" || ' for ' || "Character_Attack" ||' Damage' );
dbms_output.put_line ("Enemy" || ' Has ' || "Enemy_Health" || ' Health Remaining ');
CASE WHEN "Enemy_Health" < 0 THEN dbms_output.put_line ("Enemy" || 'Has Fainted' || "Character" || 'Wins!');
ELSE CONTINUE;
EXIT WHEN "Enemy_Health" < 0;
SELECT "Character_Health" - "Enemy_Attack" INTO "Character_Health" FROM dual; -- Villain hits Hero
dbms_output.put_line ('');
dbms_output.put_line ("Enemy" || ' Hits ' || "Character" || ' for ' || "Enemy_Attack" ||' Damage' );
dbms_output.put_line ("Character" || ' Has ' || "Character_Health" || ' Health Remaining ');
CASE WHEN "Character_Health" < 0 THEN dbms_output.put_line ("Character" || 'Has Fainted' || "Enemy" || 'Wins!');
ELSE CONTINUE;
EXIT WHEN "Character_Health" < 0;
END LOOP;
END;
END;
I found some errors
1. Syntax for case is:
CASE [ expression ]
WHEN condition_1 THEN result_1
WHEN condition_2 THEN result_2
...
WHEN condition_n THEN result_n
[ELSE result]
END CASE
Learn more:
- simple case statement
- searched case statement
CONTINUE stops processing loop and starts it from the begining, so your logic is corrupt - only Hero is attacking.
You need space after "Fainted"
It's better to use IF in this case:
IF "Character_Health" < 0
THEN
dbms_output.put_line ("Character" || 'Has Fainted. ' || "Enemy" || 'Wins!');
EXIT;
END IF;
It's not mistake, but you don't need select into from dual if you want to change value of variable.
Last but not least- i don't like how you use variables. "Character_Health" is similar to 'Character_Health' or '''Character_Health'''. Better use names like characterHealth or character_health.
My version would be something like that:
DECLARE
v_Character VARCHAR2(255) := 'Hero' ;
v_Enemy VARCHAR2(255) := 'Villain';
v_Character_Health NUMBER := 100;
v_Enemy_Health NUMBER := 25;
v_Character_Attack NUMBER := 10;
v_Enemy_Attack NUMBER := 5;
v_nl VARCHAR2(1) := chr(10);
BEGIN
dbms_output.put_line (v_Character || ' (' || v_Character_Health || ') VS ' ||' '|| v_Enemy || ' (' || v_Enemy_Health || ')' || v_nl) ;
dbms_output.put_line ('FIGHT!' || v_nl);
LOOP
v_Enemy_Health := v_Enemy_Health - v_Character_Attack;
dbms_output.put_line (v_Character || ' Hits ' || v_Enemy || ' for ' || v_Character_Attack ||' Damage' );
dbms_output.put_line (v_Enemy || ' Has ' || v_Enemy_Health || ' Health Remaining' || v_nl);
IF v_Enemy_Health < 0 THEN dbms_output.put_line (v_Enemy || 'Has Fainted. ' || v_Character || 'Wins!'); EXIT;
END IF;
v_Character_Health := v_Character_Health - v_Enemy_Attack;
dbms_output.put_line (v_Enemy || ' Hits ' || v_Character || ' for ' || v_Enemy_Attack || ' Damage' );
dbms_output.put_line (v_Character || ' Has ' || v_Character_Health || ' Health Remaining' || v_nl);
IF v_Character_Health < 0 THEN dbms_output.put_line (v_Character || 'Has Fainted. ' || v_Enemy || 'Wins!'); EXIT;
END IF;
END LOOP;
END;

PL/SQL - Create tables based on cursor using execute immediate?

I've written the following code that selects some student test data and using a cursor, inserts it into a table.
What id like to be able to do is create one table for each student and insert their relative data. This could be one row or multiple rows.

I've played around with it for the last couple of days and cant get it to work. The closest i can get is to create the tables and insert the first row only, generating an error when the loop tries to create a table that already exists.
Any help would be awesome
Thanks folks
Ben
Outcome: 1 table for each student (unique by name).
The create table ... is now inside the loop surrounded by an exception block. If the table already exists, the exception (ORA-00955) is handled.

Grafros answer looks good, but i strongly recommend to take a look at DBMS_ASSERT with DBMS_ASSERT.ENQUOTE_NAME or DBMS_ASSERT.ENQUOTE_LITERAL whenever you have take abitrary strings and use them in execute immidiate.

oracle dynamic query fetch cursor variables through sql

Little help needed. i have a dynamic query that outputs 4 column names and two table names into 6 cursor variables. Now i need to use the cursor variables to select the first 4 columns and then from the two table names using the cursor variables since those contain the data think something with a fetch through query using a variable that contains the query but i don’t know how to go about that. here’s what i have now i just need to fetch the cursor variables and runt hem into a query
DECLARE
arow VARCHAR2 (1000);
column1 VARCHAR2 (50);
column2 VARCHAR2 (50);
column3 VARCHAR2 (50);
column4 VARCHAR2 (50);
table1 VARCHAR2 (50);
table2 VARCHAR2 (50);
match VARCHAR2 (50);
match1 VARCHAR2 (50);
sql_statement VARCHAR2 (500);
BEGIN
FOR arow IN (SELECT column_name_old,
column_name_new,
column_name_old_2,
column_name_new_2,
table_name_old,
table_name_new
FROM A550003.META_DATA_TABLE)
LOOP
sql_statement :=

|| 'SELECT '

First of all you sql_statement is wrong. You should set the value of this variable to sth like this (when you will get all needed names):
sql_statement := 'SELECT '
|| column1
|| ', '
|| column2
|| ', '
|| column3
|| ', '
|| column4
|| ' FROM '
|| table1
|| ', '
|| table2
|| ' WHERE '
|| -- JOIN_CONDITION
And then you can use EXECUTE IMMEDIATE statement:
EXECUTE IMMEDIATE sql_statement
INTO col1_val
,col2_val
,col3_val
,col4_val
;
Of course variables col[1..4]_val have to be declared.
Also watch out for SQL Injection.
It must be this:
sql_statement := 'SELECT '
|| column1 || ', ' || column2 || ', ' || column3 || ', ' || column4
|| ' FROM ' || table1 || ', ' || table2
|| ' WHERE ' || column1 ||'=' ||column2||'(+)';
EXECUTE IMMEDIATE sql_statement INTO col1_val, col2_val, col3_val, col4_val;
or preferably
sql_statement := 'SELECT '
|| column1 || ', ' || column2 || ', ' || column3 || ', ' || column4
||' FROM '||table1||' LEFT OUTER JOIN '||table2||' ON '||column1||'='||column2;
EXECUTE IMMEDIATE sql_statement INTO col1_val, col2_val, col3_val, col4_val;
For debugging DBMS_OUTPUT.PUT_LINE (sql_statement); will be usefull!
Then you don't need a Ref-Cursor, simply do:
BEGIN
For aRow in (SELECT * FROM a550003.meta_data_table) LOOP
sql_statement := 'SELECT '||aRow.column1||','||aRow.column2 ...
END LOOP;
END;
