This is a sample table and sample data only. I have three tables:

CREATE TABLE EMP_TBL
(
  EMP_ID INT GENERATED BY DEFAULT AS IDENTITY,
  EMP_NAME VARCHAR2(50) NOT NULL,
  PRIMARY KEY (EMP_ID)
);
CREATE TABLE BRANCH_TBL
(
  BRANCH_ID INT GENERATED BY DEFAULT AS IDENTITY,
  BRANCH_NAME VARCHAR2(50) NOT NULL,
  PRIMARY KEY (BRANCH_ID)
);

CREATE TABLE EMP_BRANCH_TBL
(
    EMP_BRANCH_ID INT GENERATED BY DEFAULT AS IDENTITY,
    EMP_ID INT NOT NULL,
    BRANCH_ID INT NOT NULL,
    PRIMARY KEY (EMP_BRANCH_ID),
    FOREIGN KEY (EMP_ID) REFERENCES EMP_TBL(EMP_ID),
    FOREIGN KEY (BRANCH_ID) REFERENCES BRANCH_TBL(BRANCH_ID)    
)


INSERT INTO EMP_TBL (EMP_NAME) VALUES ('MNOP');
INSERT INTO EMP_TBL (EMP_NAME) VALUES ('ABCD');
INSERT INTO BRANCH_TBL (BRANCH_NAME) VALUES ('SALES');
INSERT INTO BRANCH_TBL (BRANCH_NAME) VALUES ('LOAN');
INSERT INTO BRANCH_TBL (BRANCH_NAME) VALUES ('HR');
INSERT INTO EMP_BRANCH_TBL (EMP_ID, BRANCH_ID) VALUES (1, 2);
INSERT INTO EMP_BRANCH_TBL (EMP_ID, BRANCH_ID) VALUES (2, 3);

I want count of employee in different branch. How can I do that?

branch_name count
SALES           0
LOAN            1
HR              1
